Antique silvertone and rhinestone dress or shoe clips

This is an antique gorgeous pair of silvertone and rhinestone, either dress or shoe clips from the 1920s or 30s. Marked with a patent pending number, they are in amazing condition considering the age, no missing stones. They have tiny sharp points on the clip to help keep them secure. Measurements 1 inch long by 3/4 wide. From a smoke-free but cat friendly home. I use recycled shipping packages when possible for the environment. Thanks for looking in my closet
