I filled it with documents. You can get more documents in than with a normal 4inch binder. It will not stand up though. It is unstable. I can add a title on the front cover behind a clear cover but there is no place to add a spine title. I made a spine and taped it to the outside but the tape comes off. It doesn’t stick properly to the material. In other binders it is placed behind a clear cover for the spine too. I do not like this binder but I can use it.
