This is a listing for a waterproof sheet. Size: Approximately 194cm x 133cm (Double) I bought a box-type sheet because I replaced my mattress, and I'm listing this pad-type sheet because I won't be using it. ^ ^ There are no particularly noticeable stains, but it has been used for about a year, so please consider it if you understand this. ^ ^ I am also listing a single-size sheet ☆
