Envelopes
They are solid envelopes that don't come apart on the sides like others that I have used in the past. They are secure as you can't see the writing on the document through the envelopes. I will get these again. I would recommend these envelopes.

Better than plain envelopes
Excellent envelope. I did not realize the need for security image stamping until I became aware that there is an epidemic of stealing of mailed checks and rewriting them after washing off entries. If you cannot get to the post office and need to put checks in a mailbox this is the envelope to have. In addition the 9 1/2 inch length makes it easy to fold and insert it...

Good envelopes for bulk mailing
Well-made and reasonably priced. The sealant has no taste if you lick it closed.

Don’t Like
I must have grabbed the wrong box. What I wanted was the straight edge flap with a tear off strip; not a pointed flap that I have to lick. Will probably return the box.
