White square cardboard, set of 50 sheets These are white cardboard sheets used for packing materials at a company. They are 30cm x 30cm squares. They are thicker than drawing paper and can be used for various purposes such as crafts, handmade projects, and packing materials. The back and front have different colors (see photo 5). There are blue magic marker marks on the corners. They may appear uneven due to the reflection of fluorescent lights, but they are white as shown in the first photo. The number of sheets can be increased or decreased. However, the shipping cost is 850 yen, so the price cannot be reduced much even if the number of sheets is small. They will be packed in an inner plastic bag and then shipped in a brown paper bag. Thank you for looking.
