This is a gray semi-single short anti-mite box sheet. It seems I ordered the wrong size and it doesn't fit ( ; ; )!! It's an unused item, only washed (T . T) I have two, so if you'd like to buy both, please let me know. (In that case, I'll discount it by 300 yen in total) https://item.rakuten.co.jp/ioo-neruco/14013430/?scid=wi_ich_iphoneapp_item_share
