X-ACTO Self Healing Mats are a unique accessory that is a must-have for hobbyists and designers who frequently use X-ACTO knives and cutting tools. This cutting mat features a special surface material which allows it to absorb cuts from a sharp knife or cutting tool and then magically retain its original surface. You won’t even be able to find the cut! Preserve the surfaces around your workspace! This self healing mat also features a one inch grid pattern for accurate cutting, slicing and trimming.
