Protecting your cutting surface is the main function of a cutting mat, but there's a lot more to Dahle's Vantage Mats. Constructed using five layers of PVC plastics, these mats provide strength, durability and longevity for all your craft and hobby needs. The benefits are a flat, even surface to work on and a mat that lasts a long time. Vantage Self-Healing Mats are designed not only for alignment and surface protection, but are also self-healing - which prolongs the life of the mat and allows cuts to virtually disappear. For alignment, each Vantage mat contains inch and metric measurements on the top surface as well as 1/2" grid lines. They also include scale lines for making diagonal cuts. These markings will ensure your cuts are straight, square and to the exact size you need. Vantage mats are the perfect work surface for adults and children for cropping photographs, cutting, drawing, sewing and tracing. For versatility, Vantage mats can be used on either side. They are found in a variety of sizes and are available in black, blue and the industry's only crystal clear - which is virtually transparent.
