They are definitely not security envelopes! I had to fold a paper around a check before mailing it!!

Great quality and price. Run through my laser printer easily with no jams.

These are nice self sealing #10 envelopes

These envelopes are hands down the best quality, and the best value anywhere. There are the heavier weight paper, and the easy seal makes it so much easier. Don't tell Sam's Club, but they are also under priced! What a great buy! Highly recommend.

Envelopes are very reasonable in price especially being security and self seal. My only dislike is when stuffing the envelopes is the edges inside can cut your letter. Just have to be careful when putting letter inside. I have mastered the technique. So I will keep buying these envelopes.

We have ordered these envelopes for several years now and the quality remains consistent. We do a large mailer of about 15,000 pieces every January. The envelopes are of good quality and the peal and stick works very well. Very good price which keeps our marketing campaign costs down. Thank you for continuing to provide these envelopes to your members.

Good quality. Great price!

The adhesive does not stick. I had to tape each one.

This is such a good buy. I am doing a lot of letter writing and the envelopes are needed.

I am happy that I found this here. I priced these everywhere and this is easily the best value.
