Although gender-based and sexual violence can happen to anyone, women and children living in conflict and post war areas are at higher risk. Invi and NGO Help a Child work together to make the Invi Bracelet available in an inclusive awareness program.

invi smell academically researched and works

The unique repellent smell that is used in the Invi Bracelet has a significant effect on reducing sexual arousal, according to new research. This first of its kind study publicated in PLOS ONE suggests that smell can be used as an effective self-defense method in situations or attempts of sexual assault.

Interview in the Dutch Financial papers

In this interview with the Invi’s founder, Roel van der Kamp, you can read about how it all started. Roel talks about how the Invi Bracelet was created and how he found out about its disruptive effect firsthand (Dutch Only).

Check these video’s to see people’s reaction to invi’s foul scent.

People find it often hard to understand how smell can be used for self-defense. We hit the streets to show you how people respond to the Invi scent. In the responses you can see clearly its repellent effects and how it triggers the disgust reaction. We still feel a bit guilty though;)

Impact study of the invi bracelet in Rotterdam

Together with independent research partner Risbo and the Municipality of Rotterdam, Invi executed a pilot study to research the social impact of the Invi Bracelet. The study finds that people wearing the Invi Bracelet feel safer and more confident.

The toolkit ‘dare to share’ helps to start the conversation

Talking about sexual violence is not easy, while sharing is vital for signalling, healing and prosecution. This toolkit is developed to provides guidance for both the narrator and the listener with the aim to create a constructive moment of sharing.

We invite you to join the strong people, wear the Invi Bracelet, promote our values and support our social initiatives.

Caution

The Invi Bracelet contains a breakable capsule filled with a FOUL-SMELLING SUBSTANCE which is released upon activation. 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 alarm others in the surrounding. The released dose is not intoxicating, but may cause headaches or dizziness. Breaking the capsule can result in the release of micro droplets and glass fractions. Be careful with eyes. The content may cause irritation of the skin, eyes and/or respiratory tract. The smell can be washed off with water and soap. Prolonged exposure in small spaces of less than 50m3 should be avoided. Extra caution is required when people: (I) have respiratory diseases/COPD (e.g. asthma); (II) are hypersensitive (HSP); (III) have skin diseases where the bracelet is worn; or (IV) are highly allergic. KEEP OUT OF REACH OF CHILDREN. This product is not intended as a toy and a minimum age of 14 is advised. Do not give the bracelet to others without these instructions. Irresponsible use of the bracelet and the gas-like smell may have serious (financial) consequences including (I) panic reactions of bystanders resulting in injuries; (II) evacuations (aircrafts, buildings or other public areas); (III) loss of income (bars and restaurants); (III) deployment of emergency services; (IV) damage to clothing or other properties, including those of others. DO NOT CARRY IN AIRPLANE CABIN. Carrying the Invi Bracelet on an airplane is at your own risk. In case you do, it is recommended to carry the bracelet in an air-sealed plastic bag, in a shock-proof place and only in the check-in luggage compartment of the airplane.

Warranty

Normal use ensures you can wear the Invi Bracelet for years due to its robust design, patented safety mechanism and use of high quality materials like stainless steel. 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. 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.

The bracelet is warranted against defects in material and manufacturing of the housing for 1 year from the date of purchase. The lifespan of the smell is at least 5 years.
