This rimfire target is safe, small, yet VERY loud. This product does not have the same properties of standard Tannerite rifle targets. However they do pass drop-tests and are safe with any normal handling procedures. They won’t explode from a flame or cigarette, they can burn at a fast rate if they come in contact with fire. Each package includes the two easy-to-mix components and separate target containers for a total of 13 or 15 targets
