This is the gift box I received when I got the Haru Urara sleeper. The design is very cute. How about using it to store small items? I'm measuring it myself, but it's about 30cm wide, 23cm long, and 7cm high. I haven't used it for anything other than receiving it as a gift, but there are a few black marks on the outside of the bottom, on the left and right sides, and a few vertical lines on the upper right side of the surface. (Please check the photos 7, 8, and 9.) I think it's not very noticeable for everyday use.
