Polymer clay flat round disc bead, with black and white yin yang symbol, approximately 12mm (wide) x 8.5mm (thick), sold per piece. In Chinese philosophy, the yin and yang symbolises two complementary forces existing side by side. Please note that as these pieces are hand made, they vary slightly from piece to piece. In particular, the drill hole for these beads varies considerably - expect it to be going in a different direction from bead to bead. Eg the bead pictured has the hole going from top to bottom - your bead may have the hole going from side to side. Great for making projects with kids.
