I purchased this item on Rakuten for 3880 yen. I accidentally bought two of the same item. I took this one out of the bag, but it has hardly been used. I'm using it for my mother, who has a compression fracture, and she seems to like it very much m(_ _)m This item has hardly been used, but it was taken out of the bag and stored, so please understand. This product is highly recommended for those suffering from lower back pain! The cover can be washed with a zipper.
