Double-Sided, Self-Healing Rotary Mats* are designed for use with OLFA rotary cutters to help extend the life of your rotary blade. Perfect for crafters or makers seeking a superior cutting surface to enhance any cutting projects. Constructed with a triple-layer heat welding process for long life, the 1.5mm thick, self-healing mat protects surfaces beneath the cut. Each mat is double-sided with markings on the front for precise cutting and a blank back for general cutting.
