It served the purpose I purchased it for BUT I was very upset to find that the majority of the envelopes were glued together on the inside because the seams were overglued and it leaked in to the inside of the envelopes.
I got these folders to laminate and use as a means to send home weekly work to my students' parents. They work great but are a little thin even with the lamination. Some of the envelopes have started to rip at the sides already. So just be careful when putting or taking things from the envelope.
We used these envelopes to provide information to participants in a reunion. We packed them full of stuff and they help up well. Also the size of the envelopes made them easy to fill and refill. This is the second reunion for our use of these envelopes.
