Thank you for viewing! I also have other sleepers, and this one is in a clean condition with little use. It's made of warm microfiber material and has a zipper, making it easy to put on and take off. I purchased them at Akachan Honpo for about 3,000 yen each. I can ship quickly! Discounts are available only for bulk purchases, so please feel free to comment if you have any questions. Thank you very much.
