The beads are hand formed and are coin shape. The beads measure about 13-15 mm wide. These beads have been sanded and glazed. The holes are drilled thru the center of the bead as shown in picture 4. The white spots are glare from taking the pictures in full sun and not on the beads. This listing is for 2 or 4 (Select at Checkout) handmade polymer clay beads. I make these beads one at a time and no two are exactly alike. Thank you for looking at my handmade beads.
