Cutting mats are double sided and self healing.
A cutting mat is used both to protect the surface you are cutting on, and to provide measurement guidelines and references to ensure a clean and straight cut. It is useful in a variety of projects and is considered an essential for accuracy in many crafts.
These protective cutting mats are made with a resilient vinyl that heals so completely it can be used as a writing/drawing surface, even over previous cut lines. It can be used on both sides and it has a metric printed grid pattern on both sides.
