I am selling this item as "junk" because even after inflating it, the air gradually leaks out when weight is applied (though it doesn't completely deflate). However, even with some air loss, the internal urethane provides sufficient thickness, and it served as a mat. I used it without issue for sleeping during camping trips. Because it's 10cm thick, it can be used as bedding without much problem if there aren't large rocks where you set it up. Includes a storage bag. Washed. ※The photos show the item compressed without air. Even after inflating it and some air leaking out, it will be more inflated than in the photos. 【Important Notes】 ① The condition is as shown in the photos. Please be aware of this if you are sensitive to imperfections. ② Due to the low price, which includes shipping, please refrain from price negotiations. Also, because of its size, it will be shipped in "simple packaging" using a 45L garbage bag. Please understand this in advance. ③ Shipping costs 1,700 yen, and there is a 100 yen collection fee, so please refrain from price negotiations.
