B4 copy paper, approximately over 2000 sheets A3 copy paper, approximately over 400 sheets Thickness: 4cm (when opened) These copy papers have been used and stored at home for a long time. The papers in the first and second layers, wrapped in white and brown paper, are a mix of pure white and 85% whiteness. There is some soiling from storage, and I have tried to show the soiled areas as much as possible (photos 3-6). 3rd layer: Stored in original packaging, approximately 35 sheets. 4th layer: Unopened, but the packaging has scratches, stains, and tears, 500 sheets. 5th and 6th layers: Opened, used a few dozen sheets. Thickness: approximately 4-4.2cm. 7th layer: A3, stored in original packaging. Thickness: approximately 4cm. Please understand that these are used items. Thank you.
