This is my new favorite office item!! I have never been so organized! I bought 3 sets and have shared some with staff for project management. It is EXTREMELY helpful in managing bookkeeping paperwork.
In an office environment the construction is fine - but it is definitely not designed to travel / get wet. I was somewhat concerned about the fact that there isn't anything to hold in the papers, but it has become my favorite feature! I also LOVE that each section expands up to maybe 1 1/2" for larger sections.
I never want to be without this product again! I am perhaps the most naturally disorganized person in the world, but by using several of these for each of the different areas of responsibility, I know EXACTLY where my papers are!
