All covers except 2 white faux Pearl are different sizes and/or patterns with decorative textured designs, black stones or enamel, or glass center domes. Back hinge clip opens to fit over and snap closed over a button. Six are large enough to fit 3/4” buttons and the others will accommodate 1/2” buttons. Two have oval black beads of unknown material and two have what appears to be black enamel centers. Backs have some visible wear marks but front sides on all are in excellent condition. See photos for details.
