This is the most compact shot-shell storage solution possible because it is designed so that the shells are stacked on their side, keeping them organized and easily accessible. The lid, essential when storing and stacking, can be completely detached during use for ease of access to the shells. Made of clear, durable, high-impact polypropylene, it can protect and prolong the life of your ammo. These storage boxes fit most belt style shell carriers and holders. The stackable design helps keep your reloading bench organized. They come with a reloading label and will hold 25 rounds of 12-gauge shells, 2 3/4" loaded shells. There are four to the pack.
