One single and one double size sheet with waterproof function. - Size: Single size 100cm x 200cm - Size: Double size 150cm x 200cm - Material: Pile: 100% cotton, Base: 100% polyester - Elastic bands on all four corners Thank you for viewing. These are the unused sheets remaining from a purchase of two of each size, with one of each having been used. I purchased these about 5 years ago and have stored them in a closet. The packaging is not sealed, so dust may have gotten in. Please refrain from purchasing if you are particular about the condition, as these are not completely new.
