These are stunning, graphic batik beads, adorned with a striking African mask in a larger size. 25mm x 25mm square with a 1-2 mm vertically-drilled hole. Since these are handmade, there may be some variation in thickness. (Most are 3-4mm, and slightly thicker in the middle of the bead.)
These are ebony on ivory batik bone in an ebony frame tablet bead. You get a package of 8 beads.
