100% self-healing and anti-slip but are not both mats. And in particular glass or lacquered MDF surfaces shift such mats ever happy when you exert too much pressure with your hand or a cutter on it. Otherwise, however, they are extremely stable. One can try to bend and then go back again and again to its original planar shape. So they do not slip, I adjust them happy times at the corners with thin selbtklebenden / self-release power Stripes.
The white scale imprints on the blue Westcott mat are abrasion resistant. The checkered fields, optionally with cm or inch specification, as well as the three 45 ° - or 60 ° angle-guides on the main page of the mat facilitate the measuring. Verso offers the Westcott also a checkered auxiliary field in cm unit (20 cm wide, 28 cm high). The material can be easily wipe off with water or a mild thinner, just in case it drips color.
One should respect any miracles. The self-healing such mats expect. Where will sleep cut, a cutting trace remains clearly visible. However, a blade is never fully through the entire mat. And each section closes mostly so that you do not go through a mogul field in further operations with the blade. Especially with filigree (model) operations which is quite helpful. Overall, I am satisfied with this A4 mat.
