These #10 EasyClose Security-Tint envelopes have become our favorite. They're well made don't stick together in the box are super-easy to seal and sell for a decent price. Can't beat 'em!
I have used this envelop style and Staples brand for several years and have been very pleased with its performance on my HP laser printer. I use approximately two boxes of envelopes per year in mailings for two non-profits and paying bills. The price and quality are the best that I have found.
These are great envelopes. Security features are nice and the tape seal on the flap works much better than those on the body of the envelope in my opinion.
I love these envelopes because no one can see what is inside the envelope. They are very secure from anyone seeing inside to see what you are sending to your customers or anyone else you may be sending to anyone any where. I love that I don't have to wet the flat to secure the envelope. There's no way you can get 400 characters to describe this product
