The Neck Lace eyewear leashes are hand braided in the USA using only the finest quality kangaroo leather chosen for its strength, durability, softness and beautiful colors. We use silicone gripper ends to provide the firmest grip on small and medium eyeglass or sunglass temples and a black wooden adjustment bead if you want to snug the leash close to your head or to make the leash shorter. Our use of the highest quality materials and handcrafted workmanship assures long life and lasting beauty. If you prefer a gripper end that slides onto the temple in front of your ear, see Neck Lace NL1000. Gripper Installation Instructions: Wet the ends of the eyeglass temples before slipping on the gripper ends.
