About the OLFA 6" x 8" Self Healing Rotary Cutting Mat (RM-6x8): The OLFA Self Healing Rotary Cutting Mat is self-healing, it reseals surface cuts for a continually smooth cutting surface. It extends the life of your blade and protects your cutting surface. A triple-layer heat welding process is used to create these rotary mats to increase shelf-life. It's double-sided to deliver accuracy and prolong the life of the mat. The solid side can be used for general cutting, while the grid line side can be used for precision cuts. Perfect for small scale craft projects when you don't need a full size cutting mat. Our cutting mat is designed for use with rotary cutters only. Not for use with fixed blade utility knives. To prevent warping, store it flat and out of direct sunlight. About OLFA: Ever since Yoshio Okada, the founder of OLFA CORPORATION, invented the world's first snap-off blade cutter in 1956, OLFA has been committed to developing practical and safe hand-held cutting tools. OLFA brand blades are made with top quality materials, forged with technologies that stem from traditional sword-making, sharpened with technologies that give a blade life, and ultimately finished with the craftsmanship that brings all of this together.
