Thank you for viewing! [Manufacturer] KOKUYO [Size] B4 (2 books with 6cm thickness, 1 book with 5cm thickness) I used these to organize handouts from my cram school. I used them to organize handouts and test papers distributed in class by subject. Since I've finished taking exams, I thought someone else might be able to use them. ▶︎ KOKUYO Tube File <Eco Twin R> B4-E 2-hole 6cm 2 books ▶︎ KOKUYO Tube File <Eco Twin R> B4-E 2-hole 5cm 1 book There is some wear and tear, such as slight warping, but they are durable and I think they can still be used.
