Used as a protective surface for cutting various materials, and to guide and provide measurements or references to ensure a straight and clean cut. Measurements are in centimetres. Double-sided and made from resilient vinyl. ‘Self-healing’ so cuts into the mat will “reseal” and the cutting surface lasts longer. A good working surface for almost any material and almost all desktop craft projects, making them very handy for not only crafters, but illustrators, calligraphers, photographers and designers too.
