What is the Invi Bracelet?

The Invi Bracelet is an award-winning self-defense bracelet designed to increase your personal safety. When activated, it releases an extremely unpleasant, military-grade scent that deters attackers, alerts bystanders up to 100 meters away, and gives you the chance to safely escape a dangerous situation.Key benefits:

  • Nonviolent self-defense alternative
  • Powerful military grade scent
  • Alerts people up to 100m away
  • Always within reach
  • No batteries or connection needed
  • Lifetime warranty
How do I use the Invi Bracelet in an emergency?

Take the bracelet out of safety mode by pressing the safety button. Place your fingers behind the clasp and pull firmly to break the capsule. Within seconds, the extremely foul scent is released, deterring attackers and alerting people nearby.

Use this moment of confusion and distraction to create distance and get away safely.

In what situations should I use the Invi Bracelet?

Only use the Invi Bracelet in threatening situations where you need to protect yourself and other options, such as escaping or calling for help, are no longer possible. For example:

  • Sexual harassment or assault
  • Stalking or being followed
  • Aggressive approaches
  • A physical attack

Always use the Invi Bracelet consciously and only as a last resort. The scent has a strong impact on your surroundings, and improper use may have consequences. Do NOT use it in crowded places such as bars or clubs if you can safely leave the situation in another way. See also the FAQ: “Are there risks?

How do you activate the Invi Bracelet under stress?

One of the biggest advantages of the Invi Bracelet is that it is always directly within reach. To act quickly in an emergency, we recommend regularly practicing with the safety button (see: video tutorial).

Our self-defense partners also have access to dummy bracelets, allowing you to practice under stress. Find a trainer near you.

We also recommend checking regularly whether the bracelet releases smoothly from safety mode and maintaining it well. See also: “How do I maintain my Invi Bracelet?

Is the Invi Bracelet legal to use?

Yes, the Invi Bracelet is legal to carry and use for self-defense under European law*. The bracelet contains no pepper spray or chemical agents classified as weapons or harmful to health. Invi’s defensive scent is designed to interrupt aggression without the risk of permanent injury (for either the attacker or victim).

The Invi Bracelet is intended only for direct threats. As the user, you remain fully responsible for careful and responsible use.

*Laws may vary by country. If you are outside the EU and have doubts about whether the Invi Bracelet is legal in your region, we recommend consulting your local authorities before carrying or using.

Are there any risks when using the Invi Bracelet?

Irresponsible use of the bracelet and its gas-like scent may lead to unintended (financial) consequences, such as:

  • Panic reactions among bystanders, possibly causing injuries
  • Evacuations of buildings, planes, or public spaces
  • Loss of income for hospitality venues
  • Emergency services deployment
  • Damage to clothing or other property, including third-party belongings

Despite the bracelet’s non-violent nature, an attacker may still react aggressively. This risk can never be fully excluded. Carrying and using the Invi Bracelet is entirely at the user’s own risk.

Can the Invi Bracelet be activated accidentally?

The Invi Bracelet features a patented safety mechanism that prevents accidental activation while in safety mode.

The safety button may occasionally be pressed by accident. Don’t worry, a very specific second action is still required to actually activate the bracelet. If the bracelet is not in safety mode, press both sides of the holder toward each other until it clicks back into place (see also: video manual).

What should I do after activation?
  1. First, move to a safe place.
  2. Remove the bracelet from your wrist.
  3. Take off any contaminated clothing and go into fresh air.
  4. In case of skincontact: wash with soap and water.
  5. A used Invi Bracelet may continue to smell for weeks. Place it inside an empty water or soda bottle and close the cap tightly to stop the scent.
  6. Always contact emergency services to report the gas-like smell. Also inform Invi via hello@invi.world
    or +31 (0)26 785 50 92 so we can offer support.
  7. Ask your local waste collection point how to dispose of the bracelet properly.
Can I wear the Invi Bracelet every day?

Yes, the Invi Bracelet is specially designed for daily use. Our three unique collections fit every lifestyle:

Invi Sport is lightweight, comfortable, and water-resistant, making it a favorite among athletes and travelers.
Invi Classic is our all-time bestseller: practical, elegant, and designed to add a touch of style to any outfit and suitable for every occasion.
Invi Bold is our luxurious statement piece, created for those with an eye for refined design.

Whether you’re walking the dog at night, exploring a new city, or heading deep into the forest for a run, with Invi you feel safer at any moment.

Can I shower or swim with the Invi Bracelet?

Yes, the Invi Sport and Invi Bold are fully waterproof, so you can swim and shower with them.

After a beach day, we recommend rinsing your Invi Sport or Bold with fresh water to remove salt and sand.

For Invi Classic, we recommend limiting water exposure. Splashes are fine, but swimming and showering are not advised. Too much water may weaken the leather strap over time and affect functionality.

Can I wear the Invi Bracelet on a plane?

So far, no issues are known when taking the Invi Bracelet on a plane. Schiphol Airport customs advises carrying it in an airtight plastic bag, placed in a shock-resistant spot, and only in checked baggage.

Please note: airlines and countries may have their own rules. Carrying the bracelet on a plane is always at your own risk.

Can I reuse the Invi Bracelet after activation?

The scent capsule inside the bracelet is single-use, but if you ever need to use it for self-defense, you’ll receive a new bracelet free of charge. With Invi’s lifetime warranty, we’ve got your back.

How do I maintain my Invi Bracelet?

Follow these tips to keep your Invi Bracelet reliable and functioning properly in any emergency.

  • Press the safety button at least once a week to ensure it opens smoothly
  • Check the strap regularly for damage and replace it in time
  • Limit water exposure for the Classic
  • Avoid hard drops or impacts. If your bracelet has taken a hard hit, contact us to replace the scent capsule

See also see FAQs: “What if it doesn’t release from safety mode?” and “Do I need to replace the strap?

What should I do if it doesn’t release from safety mode?

If the bracelet does not fully open when pressing the safety button, dirt is usually trapped between the moving parts.

Step 1: Press the safety button and pull the metal parts apart until the capsule becomes visible. Click it closed again and repeat this several times. This helps loosen dirt. Use a cloth if needed to remove the dirt.

Step 2: If that doesn’t help enough, apply one drop of silicone spray where the metal parts slide over each other and repeat step 1.

Do I need to replace the strap?

Yes, over time the straps of the Invi Sport and Invi Classic may wear out.

These straps are made of plastic and leather respectively, so long-term use can cause wear. This may affect it's functionality, for example if the strap breaks before the scent capsule snaps. This does not apply to Invi Bold, which has a steel band.

Do you notice visible wear, damaged leather, or other signs of weakening? Contact us. For €19, we replace the strap so your Invi Bracelet can last for years again.

How does the scent of the Invi Bracelet work?

The scent triggers a strong disgust response that can cause an instinctive urge to escape. This disrupts an attacker’s focus and actions, giving you valuable seconds to react and get away safely.

At the same time, bystanders can be alerted from up to 100 meters away. From a distance, the scent is often perceived as a gas leak, which has repeatedly caused people nearby to become alert.

In addition, academic research shows that the scent used in the Invi Bracelet can reduce sexual arousal, and the bracelet has already helped multiple people escape unsafe situations.

Can a bad smell really be used for self-defense?

Yes. Although no self-defense tool offers guarantees, the Invi Bracelet has helped people in multiple cases to safely escape a dangerous situation.

Inspired by nature and developed by the military, Invi's scent immediately elicits a feeling of disgust and shock. This can surprise, disrupt, and demotivate an attacker without using physical violence.

Furthermore, the scent from the Invi Bracelet has been scientifically proven to inhibit sexual arousal, and the bracelet is recommended by many self-defense experts as a tool to increase your personal safety.

What does the Invi Bracelet smell like?

Invi’s military-grade scent is extremely unpleasant and reminiscent of a very strong gassy odor. People who have smelled it often report a smell of sewage, sweaty feet, or rotten eggs. Its power lies mainly in the element of surprise, as people have never experienced such a combination of foul odors before.

Everyone experiences the scent differently, but for many people it is overwhelming and highly repulsive. Important to note: the scent is NOT incapacitating, so you remain clear-headed and can continue to act appropriately to escape the situation.

Is the scent safe for me and others?

Yes. According to a toxicological study by TNO, the released dose is safe to use. The fragrances in the bracelet are also found in everyday products or are even naturally produced by the body. To date, NO negative health effects have been observed from either academic research or practical experience.

Possible temporary effects: Headache or dizziness; Irritation of the skin, eyes or respiratory tract. Extra caution is advised for: Asthma or COPD; Hypersensitivity (HSP); Skin problems around the wrist; Allergies.

Avoid prolonged exposure in small, enclosed spaces (<50 m³).

How long does the scent last?

The scent is noticeable within seconds and, depending on ventilation, wind and indoor or outdoor use, can linger for several hours or even days if an activated Invi Bracelet is not hermetically sealed.

Depending on weather conditions, bystanders may also detect the scent from a great distance, up to hundreds of meters away.

Can I wash off the smell?

Yes. If there has been skin contact, wash with soap and water. Preferably do this as soon as possible after you have safely removed yourself from the situation.

It is best to hand wash and/or air contaminated clothing outdoors. Over time, the smell usually dissipates on its own.

What are the advantages of the Invi Bracelet vs. pepper spray?

The Invi Bracelet is a safe and non-violent alternative to pepper spray. Instead of a chemical that can cause injury, the bracelet works with an extremely repelling scent that disrupts an attacker's aggression.

In addition, the Invi Bracelet is legal and safer to use in many situations. You wear it discreetly on your wrist, always have it within reach, and don't need to aim precisely like with pepper spray.

Many self-defense trainers recommend the Invi Bracelet because pepper spray and other aggressive agents can escalate the situation or even be used against you.

What is Invi's mission?
Invi dreams of a world without sexual violence, where everyone can move around freely and safely.

We contribute to this mission by developing impactful personal safety solutions and disseminating them widely, along with knowledge about prevention and resilience. We aim to make our solutions accessible to as many people as possible, including the most vulnerable groups through our social donation program.

How are donations used?

Invi uses customer donations to distribute Invi Bracelets to the most vulnerable groups.

For example, Invi collaborates with organizations such as Red een Kind (Save a Child) to empower women in vulnerable regions where sexual violence is prevalent. We also support women who have experienced gender-based violence through collaborations with the Sexual Assault Centre, municipalities, and shelters.

Donations and bracelet distribution do not run synchronously on a one-to-one basis. Donations are saved until a project or collaboration can be set up, so that the bracelets reach the people who need them most.

Many victims have indicated that the Invi Bracelet has helped them with their recovery and building confidence. The gesture of "they are not alone" is also greatly appreciated. In this way, donations directly contribute to prevention, protection, and recovery.
