Roll a 4mm or 10mm diameter tube of polymer clay (or other clay) with this roller set top, then mark lines to cut by that are either 4mm or 10mm long.
The tiny blue polymer clay tube beads in this necklace (with seed bead in between them) were made with this set.
Tube bead roller tops can be used to roll beautiful consistently sized lentil beads. The tube bead roller top is helpful in fine tuning cane reduction to the specific height of the roller top. The base can be used to texture clay in a square, diamond, or straight lined pattern.
