You know exactly what to carry in the Shell Bag. Yep. Shells. 125 loose shotgun shells (up to 12 gauge) or three 25-count boxes. The case is handcrafted with canvas, 100 percent full-grain leather & poly inserts for rigidity, making it a tough compadre that doesn't mind being dropped, tossed or drooled on by a sleepy setter. The YKK brass zippered closures help ensure that the contents stay clean & dry in the worst conditions. Details: - Thick, durable full-grain US cowhide vegetable tanned leather - Weather-resistant 18 oz waxed cotton canvas - 430 denier water-resistant, easily cleanable nylon lining - Strong UV & weather resistant marine grade polyester thread - Antique brass hardware and YKK zippers - Mission Mercantile Lifetime Promise
