The Shark Tooth™


The Shark Tooth™ helps you hold on to your glasses—and look good doing it. And its ingenious patent-pending design is so reliable, you will feel as good as it looks.

It looks great on a neck cord or a zipper pull. It goes great with a pair of sunglasses, a badge holder or lanyard. Most importantly, it holds on to your glasses—sunglasses, reading glasses, or even safety glasses—so reliably that you will hold on to it.
