These polymer clay beads are made by the seller. There are 12 beads (4 large round = 3 cm and 8 small round). They are ready for stringing or wire wrapping, the holes are large enough for most wires. The large round bead is a good size to be made into a pendant. They are made using a combination of Sculpey III and Sculpey Premo and have a gloss finish. I use these particular beads for earring and pendant sets.
