The SABRE Law Enforcement 5.0 Mk4 Pepper Foam Canister is a high performance self defense option for those who wish to utilize less lethal defense. When depolyed, this unit produces a foam substance that impacts and sticks to the face of an attacker. Pepper foam greatly reduces cross contamination and produces a disorienting effect along with the other debilitating effects of major capsaicinoids in the foam mix.
