More than 70 sheets of thick paper (I've included 2-3 extra sheets just in case there are any B-grade ones). 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 listing them for reuse because it's a waste to throw them away. They can be used for crafting or as packing materials. They're 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. Thank you.
