They're envelopes. They were on sale. I needed envelopes. I don't like to lick envelopes and on sale they were cheaper than the ones you lick. So I bought them. I pay my bills by check because my bank is so stupid that they paid more than they were supposed to a couple of times including stuff that arrived broken or other wise messed up and I was contesting and wasn't gonna pay for (but said they were sorry). So now I send checks and although it's probably no secret there's a check inside a security envelope prevents casual snooping so I use them and i was running out so when I was in Staples looking for something else (no they didn't have it) I saw these on sale and bought them.
I send a monthly prayer/newsletter across the U.S. to friends/relatives numbers 150 or more. They look forward to this gift. It is important that the envelope and contents stand up to the rigors of the post office and the varying locations I mail to. I am soooo very satisfief with this mailing product I could not be more pleased. Many recipients do not use computers so mail delivery is very important.
