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


The Invi Bracelet contains a breakable capsule filled with an odiferous FOUL-SMELLING SUBSTANCE which is released upon activation. After activation, the gas-like smell is noticeable within seconds and can be perceptible for several hours over a 100 meters distance. The released dose is not intoxicating but may cause headaches or dizziness. During activation, small microdroplets may come out which can cause irritation of the skin, eyes and/or respiratory tract. The smell is washable with water and soap. Prolonged exposure in small spaces of less than 50m3 should be avoided. People who (I) have respiratory diseases/COPD (e.g. asthma); (II) are hypersensitive (HSP); and/or (III) have skin diseases where the bracelet is worn; or (IV) are highly allergic, should be extra cautious.
