For cutting and food prep each mat being a different color and designated with a food type easily avoids cross contamination in kitchen. So versatile, lightweight, and flexible these mats really hold up great! I already own a set and bought these as a gift. Lots of uses and dishwasher safe so I always feel they are immaculately clean. I used one under an iced 9x13 cake and not only was it a colorful base, but mat supportive enough to carry and take. They cake fit perfectly, didn't stick and mat was a great base for slicing to serve.
