Thank you for viewing! ☆*゜ This item has been stored at home without being used even once. I purchased it several years ago, but I never had the chance to use it, so I'm offering it for sale. The size is unknown because it's in a bag and sealed with tape. I believe it's lightweight, easy to carry, and made of a material that's easy to care for. Because it's thin, it may be shipped folded in an envelope. If you are concerned about this, please refrain from purchasing. I may change the shipping method from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. Thank you.
