Don’t stick
Returned then as they did not stay closed due to weak adhesive

Good Envelopes
They are pretty good but after a year or so, they lose their stickyness.

These #10 envelopes are a necessity for me and I am very happy with the way they completely seal shut.

Holds a letter
Just as one would expect, the envelope is opaque and has security. I like the self seal flap

Envelope Purchase
Needed the product. They had it at a reasonable price, as I expected because I had purchased similar items there before.

Why No Recycled Content?
It is totally lame that there was not a SINGLE option to buy business envelopes (or any envelopes) at my local Staples store that even had a hint of recycled content. I will look online to other vendors in the future.

How do you live without them??
I know everything is digital now, but I am still old fashioned enough that I do quite a bit by mail. Could not function without envelopes. We were traveling and realized I was out of #10's, hence, why these were bought out-of-state. I'm functioning again!!

New business envelopes with strip
Price outrageous for a “Box”!! Don’t like the strip. Glue closure more accessible for putting in documents.
