A5 size printer paper, white, 1000 sheets (500 sheets x 2 packs) KB paper is a type of copy paper, often referring to environmentally friendly products. It is neutral paper, which prevents degradation due to oxidation and offers excellent preservation qualities. A5 size (148mm x 210mm) is commonly used for notebooks, planners, books, magazines, booklets, pamphlets, menus, flyers, delivery notes, and purchase orders. It's half the size of A4, making it easy to carry and convenient for organizing information in limited spaces. I am selling this because I accidentally purchased the wrong size. Please feel free to use it.
