JoanneS. I am not sure since I have not had to replace any of my mats at this point. The white one came with the long stripping cutter but the rectangle came with the grey mat. It has bowed and tunneled the cut marks already and I have not used it as much as the stripper. But when the time comes, I will email Accuquilt, who I might add are immediate in responding to questions. More of us need to buy American products and keep our jobs here. I truly support this company and anything else that carries our flag. (Hum-m, I think I will start a link as to how many things we use in our home that is made in America, if that is allowed--better check with Admin first.)
