I always get these envelopes for mailing our monthly newsletters. I can run them through the printer so we save the cost of purchasing mailing labels and the extra work in running labels. I wish they had the ones that you also do not need to sea so that step could be saved as well. Also a greater quantity would be well received. This item is also typically less when purchased online so that is the preferred method but when in a bind it is generally available in the store. Much better than the generic brown ones with the clasp.
I like this size of envelopes because I mail over 100 newsletters per month for my non-profit organization. The newsletters are rather thick so they won't fit in #10 sized envelopes.
Every month I do a mailing of at least 200 pieces. I needed a good quality envelope that wouldn't break the bank. These fit the bill perfectly. They open nicely to allow 4 folded sheets to easily slide in and then all I need to do is dampen the adhesive and slide them shut!
