The purchase option allows you to select a size. The only size available is 23 x 23 x 2. This is fine because it is the size I need. However, this is no. What you get. You get select this size but you are then sent 3 different sizes. Two of which don't fit the bowls I have. I have tried to resolve with the seller but they don't help and don't want to resolve it. Frustrating and unfortunately becoming the standard for some purchases from ebay. Buyer beware.
