Our matchsafe is a watertight aluminum capsule with a button compass and lanyard. The O-ring ensures a moisture proof seal, and is replaceable. With an outside diameter of 7/8", OAL is 3.85" and there is approximately 3" of usable storage on the inside, so there is plenty of room for matches, emergency money or whatever else will be of value in your particular environment.
Satin aluminum is the standard finish, blasted finish is available on request for no charge, and GunKote finishes are optional for an additional charge. Aluminum body and cap made in the U.S.A.
