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!!
