I bought these in the past and was satisfied with them. However upon buying them again I see that they are of lesser quality now specifically there is far less adhesive on the flap. There is only a thin strip of glue and the envelope does not seal as securely as it used to. Clearly an effort to save on manufacturing costs but now a poor value for the customer.
I've purchased these envelopes several times. They do not seal well is my only complaint = I have to use scotch tape on the corners to make sure they don't rip/open when mailed.
