Although most of my bills are paid online I still have some that need checks. I hate licking envelopes (paper cuts on the tongue - ouch!) so these work great for me.
We use this envelope for large mailings. It is easy to work with. Have no trouble keeping it sealed. It is nice if you forgot to put something in the envelope after you just sealed it. It will peal open easily and then reseal. You can only do this once. After about two minutes they are really sealed. If you tried to reopen them they would be ruined. Being a security envelope you cannot see through them. I really like these envelopes because they are mess free and they are easy to peel. I would recommend these to anyone.
Hey what can you say about envelopes they either work or they don't. This is the 2nd time I have purchased this particular envelope from Staples. I was worried that they might have discontinued it in the few months between my purchases; which has happened to me. I really like the security feature and the pre-glued flap. I haven't had any problems with them coming open during mailing. However you can open them right after sealing in case you forgot to add your letter :)
I would not buy these if you still carried a better quality product as you used to. I have had the flap come open between my home and the post office. I have small stickers with our organization's logo and I use them to seal the ends of the envelopes. That gets to be a pain when I send out dozens of them each month.
