frequently asked questions

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. Put your fingers behind the clasp and break the capsule with a firm pull.

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.

For self defense only! Use the Invi Bracelet only as a last defense option. Try to get away, scream for help or assess 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 assault.

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.

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.

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.

Always call emergency services after use to inform about the gas-like smell. Please also inform Invi via hello@invi.world or +31 (0)26 785 50 92
