This set includes 6 steel craft dies designed to perfectly cut around the matching stencil set. Heres a handy tip: die cut your paper first, then secure the pieces on a blending mat before placing the stencil on top to blend your colors. This trick helps you achieve crisp, clean edges every time! The dies come pre-clipped and are made from durable, high-quality 100% steel. Theyre compatible with most die-cutting machines on the market.
