Star micro clay cutter for polymer clay. Material: These cutters are made either from resin or pla plastic which is durable but can be damaged if mistreated. Not food safe. Sizes: Cutting edge 0.4mm Available in size - 8mm Sizes are taken at the longest points of the final cut (not of the actual cutter itself). Please note: colours of cutters will vary. Using your cutter: Roll out your clay onto a tile to help the clay stick to the tile and not your cutter. To help avoid getting clay stuck inside the cutters, place a piece of cling wrap on top of the clay and then use the cutters to cut out the shapes. Or lightly dust your clay with baby talc, flour or cornstarch before pressing the cutters into the clay. Apply even pressure to the whole cutter. Give cutter a slight wiggle to help release from the clay. Cutter care: Wipe with a soft cloth after each use. Wash with lukewarm (never hot) soapy water.
