Self-healing mats are specialized surfaces designed to repair themselves after being cut or damaged. Made from materials like polyurethane 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 printed grids or measurements, aiding in precise cutting and alignment. They are popular among hobbyists and professionals alike, as they help prolong the life of the workspace and reduce the need for frequent replacements.
