Progressive International is your source for the widest range of functional, inventive, and fun kitchen tools and great ideas put into practice. Our in-house designers spend hours in the kitchen coming up with ways to improve on a variety of traditional tasks and tools. Established in 1973, our commitment to quality and service allows us to offer a broad selection of quality kitchenware and other household products. This Progressive set of 3 warp resistant dual sided mats maximize available cutting surfaces in the kitchen. Each reversible mat measures 11-inch by 15-inch. They are color coded to prevent cross-contamination and are 50-percent thicker than most mats. This added thickness helps prevent warping and curling edges when cleaned in the dishwasher.
