Thank you for viewing. This is a single-size gray, fluffy, and soft敷きパッド (shiki-pad, a type of mattress pad). It was originally thin with short pile. It doesn't have elastic bands, but it has non-slip material on the back, so it's easy to use, just by placing it on the bed. The tag is faded. I bought it a few years ago and used it for one season. After that, it has been stored at home. Please only purchase if you understand that this is a used item.
