The Invi Bracelet is a self-defense product that can be used as a nonviolent way of self-defense. After activating the bracelet a foul-smell is released which repels an attacker and alarms people in the surroundings.
Key characteristics that make the Invi Bracelet unique:
- Strong repellent effect from close by
- Alarms others over a 100 meter distance
- Always within hand reach
- Small and stylish Dutch design
- Reliable patented safety mechanism
- No power source required
The Invi Bracelet can be activated to release a repellent smell. It contains a capsule which can be broken once in case of emergency.
To unlock the bracelet from ‘safety mode’, press the safety button. Place two fingers at the back of the clasp and bend your wrist slightly inward. The capsule holder must be able to bend over the ‘bulge’ of your wrist. Then break the capsule by gradually applying more and more force with your fingers (see videomanual).
After activation the gas-like smell can be noticed within seconds, lasting up to several hours. The smell works disturbing and repellent. However, reactions differ per person. The smell can reach over 100 meters distance and can help to alert others in the surrounding.
The Invi Bracelet is designed for all.
Most people wear the Invi Bracelet to feel safer, more confident and stronger.
You can use the Bracelet for everyday wearing, for travel and for sport activities.
A minimum age of 14 is advised.
For self-defense only! Use the Invi Bracelet only as a last defense option. Try to get away, scream for help or asses other options to get into safety as quickly as possible. The product is mainly intended for, but not restricted to, self-defense in the case of sexual violence.
Please keep in mind that irresponsible use of the bracelet and the gas-like smell may have serious (financial) consequences (please also refer to the section “Are there any risks?”). The wearer is responsible for assessing the situation prior to using the bracelet. For example, do not use the Invi Bracelet in a crowded bar if there are other options to ward off a touchy drunk.
Irresponsible use of the bracelet and the gas-like smell may have serious (financial) consequences including:
- Panic reactions of bystanders resulting in injuries
- Evacuations (aircrafts, buildings or other public areas)
- Loss of income (bars and restaurants)
- Deployment of emergency services
- Damage to clothing or other properties, including those of others.
Although use of the Bracelet is not an aggressive or violent act towards an attacker, be aware that an aggressive response can not be excluded. Please also refer to the section “How does the smell work?” and “Is the smell safe to use?”
One of the major advantages of the Invi Bracelet is that it is always within hand reach.
Nevertheless, we advise to practice using the safety button to ensure quick activation when required. By making yourself acquainted with the first two activation steps (see manual) enables you to respond more adequately in a stressful situations.
It is also advised to regularly check whether the bracelet goes quickly out of safety mode after pressing the safety button (please also refer to the section “What about maintenance?”).
Invi designed a patented safety mechanism making sure the bracelet can not be accidentally activated while in safety mode.
Sometimes the safety button can be triggered accidentally. No worries, also when the bracelet is not in safety mode, quite some force is required to activate it. Just press both sides to put the bracelet in safety mode (see manual).
Go to a safe place. Remove bracelet from wrist. Remove contaminated clothes and move to fresh air. In case of skin contact: rinse skin with water and soap for at least 15 minutes. In case of eye contact: rinse eyes with water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Consult a doctor when symptoms persist. People with respiratory diseases can use their own medication.
Do not throw the Invi Bracelet away, but preserve in an empty water bottle (with closed tap) or air-sealed plastic bag, as it could be used as evidence.

Until this date we haven’t had any problems when carrying the Invi Bracelet on an airplane. Dutch Airport Security advised to carry the bracelet in an air-sealed plastic bag, in a shock proof place and only in the check-in luggage compartment. Since some airliners can follow their own legislation, we do want to emphasize that carrying the Invi Bracelet on an airplane is at your own risk.
You can extend the life-span of the bracelet by treating it with gentle care. The bracelet can respond to certain environmental influences. It can oxidize and thus discolor when exposed to humidity, carbon dioxide, the sulphur content of the air or to sweat, perfume, cleaning products, acids or body lotion.
Dirt from ordinary use can sometimes jam the safety release mechanism. Therefore it is important to press the safety button once a week to see if it opens smoothly.
A cleaning tissue can be used to wipe off dirt trapped between the inner parts. If this does not help, silicone spray will do the trick. Spray one drop between the moving parts. Now press the safety button and slide both parts over one another. Repeat this a couple of times to to ensure the silicone spray spreads out evenly.
For Invi Bracelets with a leather band, avoid direct contact with water and/or detergents to maintain the quality of the leather. Even though the bracelet is shockproof, avoid dropping. Store at a cool and dry place when not wearing.
