The P2P Core Defense .68 Caliber Inert Powder Rounds are less than lethal projectiles designed to shoot from your P2P defense launcher. They have a steel core encased in an inert powder with a hard, outer shell designed to split open upon impact. The result is a hard-hitting self-defense round that gives you peace of mind. These are great for training or in areas where pepper is restricted. Each pack contains 100 blue/black inert powder balls.
