I used this daily for about six months starting last summer. I've washed it several times. The zipper has some loose threads, but there are no problems with its use. (Image 4) Both the mat and the cover can be washed completely. I will ship it in the cleanest condition possible, but please understand that it has been stored at home. Also, please only purchase if you understand that this is a used item. Original price: 4980 yen
