On a recent dive trip a buddy of mine lost a very nice mask that was smashed to bits by a 2 pound lead diving weight.  This box will help you protect that Squale, Equirama, Dacor Dm30, and many more vintage oval masks.  All of the Museum's diving masks live in these protecting them from the elements and rogue weights.  The mask houses the typical vintage oval with enough extra room for a liner of paper or cloth of your choice.  I typically use a cut up cotton t shirt, but you may prefer heavy duty towels.
