MOO Carve Professional Carving Blocks are constructed of latex-free PVC, which makes them soft, pliable and safer to use than linoleum for all of your stamp carving or printmaking needs. This innovative product “cuts like butter” and will hold even the finest of detail without breakage. The soft surface will readily accept transfers but designs can also be applied directly with pen, pencil or marker. Because of their texture, blocks can be cut into smaller pieces and all sides can be utilized.
