I really like these mats. They're the perfect size for placing on your workbench to intercept epoxy spills or whatever. Oddly enough, I ordered the light gray mats and what I received was beige mats instead, which is even more odd when you realize beige isn't one of the color options (?) But I really don't care about the color, I just like it that they're so useful. As others have pointed out, one side of the mats is smooth and therefore sticky silicone with the other side having been scuffed upSee full review
