Keep your loose sheets together with the Pocket Folder from Kokuyo. These folders are especially helpful if you have sheets that need to be categorised (different projects or different subjects).
FOR THE A4 SIZE:
A pocket folder that brings together the convenience of a clear booklet and a clear holder. 8+2 pockets make it easy to store your documents. 2 cover pockets hold up to 10 documents, 8 inner pockets accommodate 20 cards, and a stopper in the middle pocket keeps things safe and secure. The Novita design lets you adjust the width of the paper inside, and when the amount of documents decreases, you can resize the back and fold the cover over perfectly.
