Nice adjustable glasses holders with wire straps. These were a little more heavy duty than we were expecting and worked great for my daughter. The strings secure well to the arms, and the wire is adjusted to full length the gasses sit around your chest bone. When the glasses are on, the wire sits a bit off the head vs draping on the back of the neck. My daughter plays sports and these help keep her glasses in place so they don't fall off. I am happy with this set of glasses holders and they work great.
