This is a five-piece set of Nishikawa bedding featuring a Miffy design, made in Japan, and made of 100% cotton for peace of mind. All items are machine washable. The set includes a comforter, a mattress, a comforter cover, a mattress cover, and a carrying bag. I purchased this for my child's preschool, but I am selling it because I bought another bedding set. I took it out of the bag and unfolded it, but it has never been used. - Made in Japan - Comforter size: 80 x 110cm - Comforter cover size: 80 x 110cm - Mattress size: 70 x 120cm - Material: 100% cotton Thank you for looking.
