The Cutterpillar Replacement Mat For Glow Premium & Basic is a translucent crafting and self-healing cutting mat. It's a replacement mat for the Premium & Basic boards (but also a great mat to use on its own); it even has a non-slip textured base coating. Durable PVC cutting surfaces and functional printed grids will persist through thousands of cuts. It has markings every 1/4" and 15, 30, 45, 60, and 70-degree angle lines. While this 12" by 17" mat is mainly used for sewing and quilting, it's also perfect for other crafts. Please note this is only the mat, it does not include the lightbox.
