This 3 oz. Streetwise 23 pepper foam has a very unique safety mechanism. The top flips up and with a push of your finger, the foam is released. This safety lock makes it impossible for the pepper foam to go off when not in use. The foam, instead of spray, makes it easier to hit your attacker and decreases blowback so only those who have been sprayed will be affected. With UV marking dye.
