I am using design paper. It has four pockets. It opens wide, making it easy to see the contents, and it excels in storage capacity and organization. It's convenient for sorting receipts, invoices, coins, cards, passbooks, stickers, etc. There is a risk of damage if subjected to strong loads or impacts. Please store away from high temperatures, humidity, and direct sunlight. Each item is handmade, making it a one-of-a-kind product. We cannot mass-produce the same item, so we do not accept custom orders. #handmade #designpaper #accordionfile
