This 13 in x 13 in (33 cm x 33 cm) all-purpose, self-healing craft mat is AMAZING! Great for paper crafting, scrapbooking and stamping (you'll get clearer images when you rest your paper or card on the surface of this mat). It has a grid for easy alignment, and it's washable, long lasting, and safe to use with rotary cutters, piercing tools, eyelet hammers and needles. No craft box should be without one!
