The Helix Craft Cutting Mat is a high-quality A1-sized mat measuring 34 x 22.5 inches. Made from durable PVC material, this double-sided mat features self-healing properties, making it ideal for various crafting and sewing projects. The ANSIO brand ensures reliability and longevity in your cutting tools collection. This is for a set of 5 Helix A1 boards - used by my daughter at uni and no longer needed cost nearly £30 each when purchased. The boards are well use have have Marks glue etc on but still in usable condition. They do need to be laid flat as due to storage are bit warped! I will late flat prior to sending. These are large and heavy so collection welcome
