[Case Fits] 55 Folding Knives, Swiss Army Knives, or Butterfly Knives. Leave the perforated spacers in for smaller knives & remove them for longer knives. For thin knives, 2 can be placed in a single slot. [Case Features] Case Club’s rugged 55 Folding Knives travel & storage case is waterproof (IP67), crushproof, dustproof, compact, airtight, shippable, and is TSA approved for checked luggage. The exterior case dimensions are 16.75″L x 12.62″W x 6.75H. This durable, heavy duty, storage case is the most versatile knife holder on the market. [Custom Foam Interior] The shock absorbing foam is a military grade closed cell polyethylene that will last a lifetime, and is PRE-CUT to perfectly fit your knives. The pre-cut custom foam fits your knives out of the box! No messy, irreversible, time consuming plucking required! [Case Hardware] Shell is made of injection molded high strength copolymer polypropylene plastic with ribs for additional structural reinforcement. 2 strong latches keep the case securely closed; 2 metal reinforced padlock holes keep your contents protected; stainless steel hinge pins for added strength; pressure relief valve for changing altitudes; rubber over-molded handle for comfort; and a gasket seal keeps out water, dust, dirt and other foreign debris. [The Perfect Gift] Great gift idea for on-the-go collectors, friends, family, travelers and most importantly… [The Competition] Don’t fall for fake “hard shell” cases! The competition will call their products “hard” or “durable” when really their products are only just molded, soft fabric zipper bags. Remember, if it has a zipper, it’s not waterproof OR heavy duty! Case Club’s 55 folding knives case is second to none in terms of detail and design. At its basic functioning, it can hold 55 folding knives. Removable and swappable pieces allow further customizations for a variety of knife sizes and types.
