Nubby Eyeglass / Sunglass Holder. Smooth but lumpy, round and bumpy, all those things make it nubby. Made with Desert Jasper gemstones, Czech glass seed beads, and mottled wooden beads, this lightweight 29 inch long glasses chain is versatile enough for male or female frames. Adjustable stretch ends make sure your glasses stay put while the rest of the chain just looks good!
