They are made by BridgePort. These 10-pocket folders are great because you don't have to hole punch a single sheet. Plus, you don't need sheet protectors. Each folder is poly and flexible.
Two pockets on each page, front and back.
Thick enough to hold all your important tax documents. Buy one for each year. Always keep your taxes going back 7 years. A relative was audited last year and he wishes he had listened to this tip.
I will move my documents in folders into these 10-pocket folders. I will store them in the crates that are holding my manilla folders now.
