My daughter used this only once. There are 4 or 5 stains on the back, as shown in the image. They are about 1 millimeter in size. I inspected everything, but I apologize if I missed anything. It was only used once, but please understand that it is a used item. There is no bad odor. I think it's in very clean condition.
