Richell Bath Mat - Doesn't Get Cold I dried it every time after use. There are some dents as shown in the photos. I think there's no problem with using it. See images 3 and 4. No mold. I've disposed of the box, so I will ship the mat in a reused cardboard box I have at home. This is a used item by a child, so please refrain from purchasing if you are concerned. Anonymous shipping.
