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

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.

#10 ENVELOPES
Staples is my “go to” store for my office (and) personal “paper” needs! Just purchased the security tinted self seal envelopes on sale! I was not aware that the envelopes were on sale, which was an added bonus! Also, just know, if you find a better price elsewhere, Staples will match it!

Easy close envelopes
They are ok, but seem very thin.
