1InTheOffice Clear Pencil Pouch For 3 Ring Binder, Ring Binder Pockets with Zipper, Vinyl, 4 Pack

I repurposed an older/smaller odd sized 3-ring binder. These worked perfectly due to the various ring hole positions. The zipper is a little tight to open, but is heavier duty than I expected for the price. Arrived nicely in packaging, no bending.I went to several stores to find the exact ring hole spacing and could not find. I am very happy with my purchase.
