LaOficina 11 Holes Semi Poly Envelope Pocket Insert Pages for Binders, with Hook and Loop Closure Pink,A4 Letter Size,5 Packs

Not happy with purchase unless I only want to store 1-3 sheets of paper. Otherwise, they are not produced to handled anymore quantity than this.

Pros - good for anything really skinny. I stuck regular notebook paper and it fits 20 pages. It fits well in my binder.Cons- the entire envelope is 12 x 9.4, so the inside fits a sheet of paper, but if you put anything thick then it has to be less than six inches.Not for what I need, but good for someone else.
