Never lose a mask again, these lanyards have the larger stainless steel lobster clasps on each end to clip to the elastic or tie backs on your mask. They are made with Miyuki seed beads. They are about 17-19 ins long, so won't hang too low when you take the mask off. Very convenient when you have to go in and out of shops. Can be ordered longer if needed. Clasps and colors will vary. Please email me if you need a certain color combination.
