Practice Spray, Inert Stream Spray - 1/2 oz can.
This canister has the same look and feel as a regular 1/2 oz pepper spray (PS-2, for example). It behaves just like a 1/2oz pepper spray too. The only difference: its content is not Oleoresin Capsicum (liquid pepper extract) but WATER.
This is perfect for practicing your defensive moves and getting used to its shooting distance, aiming and pattern of a regular pepper spray.
