Company is 3D Gizmo's
Our cutters are 3D Printed and are recyclable. They can be washed in lukewarm water (they are NOT dishwasher safe as they may warp or melt at high temperatures).
If the clay sticks to the cutter you can try dipping the cutting edge in water or cornstarch before use.
Alternatively a layer of cling-film over your clay before cutting can help prevent sticking too!
