Founder Roel tested the scent on the streets of Amsterdam, using a heavily diluted version. What you see is a disgust reflex: people flinch and step back.
The real capsule is many times stronger.
press, pull, distance
A foul smell naturally triggers disgust. You instantly want to get away. Skunks use this cleverly to scare off predators. Invi uses the same principle, with a military-developed scent hidden inside a stylish bracelet.

The extreme smell can deter and discourage an attacker. Use that moment of confusion to get away safely.
non-violent, legal and always within reach
With Invi you can act immediately in a threatening situation. Without violence and without relying on bystanders. Not a loose object you first have to find and grab, but a beautiful piece of jewellery you love to wear.
In the Netherlands and many other countries, pepper spray is illegal or heavily restricted, even for self-defence. Aiming under stress is hard, and there’s a risk an attacker takes the spray and uses it against you.
Invi is legal to carry with you.

“i couldn’t go anywhere. then i thought of my invi”
At a martial arts event, security guard Hanne ended up in the middle of a fight between two groups. She was hit, fell to the ground and got trapped. Then she activated her Invi Bracelet. The men were overwhelmed, some even started gagging, and the fight stopped. That gave Hanne the chance to get away while her fellow guards stepped in.

good to know
Can the Invi Bracelet go off by accident?
The Invi Bracelet has a patented safety mechanism that prevents accidental activation. You first have to press the safety button and then pull firmly to break the scent capsule. So even if the button is pressed by accident, the scent won’t simply be released.
Does it really work?
Yes, how Invi works has been scientifically studied. Research by the University of Groningen shows that Invi’s scent significantly reduces sexual arousal in men. There are also several real-life cases in which people escaped an attack with the help of their Invi Bracelet.
Reactions to the scent differ from person to person, and every situation is different. Invi therefore can’t guarantee success, but it does give you an extra way to defend yourself in an emergency.
Will the Invi Bracelet fit my wrist?
The Invi Classic has an adjustable leather strap and fits wrists of 15–19 cm. For wider wrists, selected models are available in XL (up to 22 cm).
The Invi Sport has an adjustable, waterproof strap and fits wrists of 15–18.5 cm. The Invi Bold comes in two sizes: S (15–16 cm) and M (16–17 cm).
Will I smell it too?
When you activate your Invi bracelet, you’ll smell it too. The scent can cause disgust but isn’t stupefying, so you can keep thinking and acting clearly. A big advantage: you know what’s happening, while it comes as a complete surprise to an attacker.
How long does the smell last?
The smell is noticeable within seconds of activation. Depending on the surroundings, ventilation and weather, it can linger for hours or even days, as long as the bracelet isn’t sealed airtight (e.g. in an empty soda bottle). The smell can also spread over hundreds of metres and help alert people nearby.
Can I take the bracelet on a plane?
According to Schiphol Airport security, it’s allowed in checked baggage. Airlines may have their own rules, so check with your airline beforehand. Bringing it is always at your own risk.
What if I’ve used it?
Did you have to use your Invi Bracelet in self-defence? Then we’ll send you a new one for free. That way Invi protects you for life.
How quickly will I receive it?
Invi Bracelets are made in the Netherlands and ship from the Netherlands every working day. Within Europe, orders usually arrive in 3–5 working days; elsewhere in 5–15 working days.
