Over 100 sheets of thick paper (with 2-3 extra sheets just in case there are any B-grade ones). Size: 75mm x 105mm Thickness: Approximately 0.3mm Color: White on the front, gray on the back. These were used as backing cards for products, and I'm listing them for reuse because it's a shame 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. Great for message cards too!
