This is a celtic-knot inspired bead of interwoven squares, 10mm in diameter with a 3mm center-hole; a perfect size for prayer-beads or charm bracelets.
If you need a bunch, you can buy them on a sprue of 8 beads together, which saves a bit of handling cost.
This design was originally commissioned by Modern Alchemy, and you can check out the finished products they make on their site for ideas or to buy some great already-finished jewelry!
