This is the second set of mats I’ve purchased. They are so good that I won’t throw out the old ones—-just stick them in my greenhouse. When Lowe’s stopped stocking them and kept saying they were out, I finally decided to contact you, the manufacturer. I LOVE these mats because they really help you relax when you’re spending lots of time in the kitchen. If shipping prices ever go down, I will go ahead and buy another set for future. By the way, the old ones did not wear out and lasted six years. The thin design pattern overlay was starting to peel in places.
