I washed it once to pre-shrink it, but it's unused. It's sold out on Rakuten. The color is brown, and the size is family size. (I selected king size in the category because it's the largest size available.) Retail price: 6980 yen [ OKIPPA Premium ] Pad-integrated, non-slip box sheet The non-slip box sheet is now available, following the OKIPPA easy-to-place, non-slip mattress pad, which won first place in the Rakuten rankings!! The OKIPPA easy-to-place, non-slip mattress pad and box sheet are integrated! If you: - Dislike the stretchy elastic... - Want a more stylish look... - Still experience slipping even with a non-slip mattress pad... - Find box sheets bunching up and uncomfortable... Then this is highly recommended for you! With the same non-slip properties, combining it with a box sheet creates a more premium and comfortable OKIPPA that is even less likely to slip!
