LION Junior Cutting Mat CM-901G is the budget-friendly solution for school and home. Thanks to microscopic rubber nubs, the surface immediately closes after a cut. The mats are double-sided and made from a three-layer construction in a sandwich design from PVC. The soft top and bottom layers, each 1 mm thick, are separated by a 1 mm thick white middle layer. The total thickness is 3 mm. Cleaning is done with a damp cloth. Do not use acids or solvents! Always store flat to prevent warping. Avoid direct sunlight and keep away from radiators. The surface is green with a printed 1 cm grid on the front. The dimensions are 900 x 600 x 3 mm.
