The polymer clay Texture Roller is made of high quality and durable material. Please wash the polymer clay Texture Roller by hand with warm soapy water or wipe it with alcohol. Dishwasher and high heat may distort the shape. These bead rollers create polymer clay in 20 mm diameter beads. Simply place a small amount of clay in the hole and easily roll it to create any shape you like. Measuring the correct amount of clay can take a long time, so it is good that depending on the clay you use, you should write down the weight so that in future uses you do not waste time looking for the exact amount. The volume of dough varies according to each environment and temperature, so we do not attach an exact measure of clay to use in this tool
