More than 70 sheets of thick paper (2-3 extra sheets are included just in case there are any B-grade sheets). Size: 18cm x 24cm Thickness: Approximately 0.3mm Color: White on the front, gray on the back. These were used as backing boards for products, and I'm selling them for reuse because it's a shame to throw them away. They can be used for creating artwork or as packing materials. They are also good for preventing damage when shipping trading cards or thin items. If you need a large quantity, please comment and I can create a dedicated listing with a 10 yen discount, but they will be shipped separately due to weight and shipping costs. However, if I have them in stock, I can also prepare 300 sheets for 1480 yen, so please consider that option.
