We need to put our patron tickets in envelopes before each show. These envelopes are just perfect! We also use them for our bills and other administrative mailings.
I have been using these envelopes for both personal and business mailing for at least 5 years. I don't know why you would want anything more unless you wanted a self-seaking variety. They do the job are easy to feed into my printer znd come out nice and clean.
I use these envelopes to communicate to supermarket managers. I sell them some items that are distrubuted by their grocery warehouse suppliers and I need to advise them of promotions as well as new items when they become available. The envelopes have to look busnesslike as these grocery managers are very busy people so the envelope cannot look like it contains a mass mailing butmust contain a personal letter giving the information to help them make the decision to have the items in their spermarket and to support the promotion.
