FOR SELF-DEFENSE ONLY. The use of this substance or device for any purpose other than self-defense may be con­sidered a crime.


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.


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. NOT COVERED BY WARRANTY: The band; damage or breakage caused by accident or dropping; lack of care; water damage and normal wear or tear.
