I'm selling these cardboard sheets, which I was keeping to exchange, but I've stopped doing that. There are many sheets, but they are not for individual sale. I will ship them with only water damage protection, and will not reinforce them. Please consider purchasing only if this is acceptable. I will include a bonus for the first people who purchase, but it will end when supplies run out. I can offer a discount within a reasonable range only if you purchase with other cardboard sheets, so please request a combined purchase. Naniwa Danshi Kento Nagao
