More than 100 sheets of thick paper (I've included 2-3 extra sheets just in case there are any B-grade items). 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 waste to discard them. 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! Thank you.
