These are the same straps that you find on all the old school rubber masks from the 50's 60's and 70's.  Modern mask straps will not work on the old Squale, DM30, Equirama and so on.  These real runner masks are direct from France and are brand new manufacture.  I would suggest that you stock up on them as they may not be available for too much longer as the old masks get harder and harder to find.
