This is general carbon paper. 20 sheets will be sent. Although unused, there are some areas where the edges are folded or torn due to storage. I think it's in a condition that won't affect use. The size is slightly larger than A4. For reference, I've included an image with an A4 clear file placed on top. Please note that the A4 file is not included. It will be shipped folded in half. There are nearly 100 sheets, so the number of sheets can be changed.
