Using for paperwork and hanging in a file cabinet. Binder rings are a bit difficult to open -- you need to push in the pieces that allow the binder to hang before you can open/close and it is still a bit tricky. Other than that, the rings line up with no gap and the items do not fall out while hanging in the binder. I would buy again and hope that they improved the rings.
Fantastic to use each day and be able to file away when through. Add tabs and your can adapt to hundreds of different uses in the office.For example: payroll, commissions, banking, projects, color co-ordinate with files, etc. Still using binders I purchased 20 years ago.
