ASP Key Defender Insert Heat OC Twin Pack

 Unlike common throwaway aerosol can defense products, ASP Defenders are  highly-engineered dispersion devices that use a proprietary, replaceable  OC (Oleoresin Capsicum) Insert. These Inserts are precision-machined  from aerospace aluminum and solid brass, and incorporate a  specially-produced valve system and patented dispensing mechanism. The  entire unit is O-ring sealed.

This Insert is compatible with ASP Key Defenders, and contains approximately six 1/2-second bursts.
