This replacement mat for the Glow Ultra is 19x26, it includes the industry’s first non-slip textured base. The very durable PVC cutting surface, along with one of the most functional printed grids you’ve ever seen, will persist through thousands of cuts. The 1/8" thick mat includes ruler measurement marks with fractions printed next to them, standard craft angles, vertical and horizontal rulers, and a metric ruler. It also goes edge to edge on the Ultra.
