Pro Bead Set 5 rolls a single bi-cone shaped bead with blunt ends. The length of the bead it can roll is 42 mm. The diameter of the centre of the bead is 17mm. This bead roller does have a bead piercing pin path through it, so the bead can be pierced through the roller, eliminating the likelihood of fingerprints, and possible distortion. Additionally there is a 1/16 inch rule on the edge of this to assist you with measuring clay according to directions, as well as s a line at the pin path to assist lining the bead up for piercing. See our Bead Rack designed to hold the bead piercing pins for curing or finish coating beads, a must have for serious bead makers!
NOTE TO POLYMER CLAY USERS: Due to the size/diameter of this bead it is prone to cracking during curing. If this happens, plunging the bead into ice water directly from the oven does close the crack, leaving a tiny fracture line. This does not always happen, but Poly-Tools wants you to know the possibility of this.
