Material: Eco Resin - 3D Printed • Size: 8 x 2 cm User Guide: To avoid clay getting stuck inside the texture, you can use a bit of cornstarch or baby powder by lightly brushing it on the clay before using the roller. Achieving the same effect can be done by placing a piece of cling wrap on top of the clay. Note: The rollers may vary in color depending on what we have available at the moment although it will always be the same brand to maintain the quality. Keep out of reach of children, adult use only.
