The Large Self Healing Cutting Mat is a great addition to any hobbyist's supplies collection. This mat is constructed of a special PVC material that will heal cuts as you make them. This will extend the lifetime of the board, and will last much longer than your average kitchen cutting mat. The large size of this mat (18 inch x 12 inch) is perfect for those precision projects, and the non-slip material will ensure you have a safe work surface. Each mat is double sided, with basic measurements, rulers and a grid. Make sure to grab one of these before your next craft project, or gift one to your favorite hobbyist.
