These eyeglass holders/necklaces are a convertible piece of jewelry. Using the attached ends, you can wear it to hold your eyeglasses. The eyeglass attachment pieces are removable from the lobster claw findings at each end of the necklace. When you remove the two attachment pieces, the necklace can be turned around and clasped together in the back with the two lobster claws. These works of art use Casual Elegance's own beads interspaced with Czech glass beads. They are approximately 29 inches in length including the eyeglass attachment pieces.
