Hidden Hollow Beads eyeglass holders are made by hand right here in this country. We provide extra rubber loops for the ends so that if one breaks you will have a replacement. We also provide a metal loop so that you can clip both ends to the loop making a convenient place to hook your glasses through or any item you are working with or carrying. It also turns the eyeglass holder into a lanyard that you can hook a badge to. The lobster claw clasps on the end of the eye glass holder also make a perfect mask holder. Just hook the clasps around the ear loops of the mask
