A self-healing mat is a specialized cutting surface designed to repair itself after being cut or damaged. Made from materials like PVC or rubber, these mats feature a unique structure that allows them to close up small cuts and scratches, maintaining a smooth working area. They are commonly used in crafts, sewing, and model-making. These mats often come with grid lines and measurements printed on them, aiding in precise cutting and alignment. Available in various sizes, a self-healing mat is an essential tool for hobbyists and professionals alike, ensuring longevity and a clean workspace.
