I purchased this at a craft store last year in preparation for school, but I didn't use it, so I'm selling it. Size: Approximately 100cm x 50cm 660 yen The material isn't listed, so I don't know. I will take measures to prevent water damage and ship anonymously♪ ◯Please feel free to comment if you have any questions! ◯Please purchase if you understand that this is a used item, stored at home, and has been inspected by a private individual! ◯I plan to compress it for shipping. Please be aware of creases! ◯Instant purchase is welcome!
