You shouldn’t be recording and monitoring my purchases. It’s creepy and weird and upsetting.

Per piece
They sell every pieces as well so you do not need to buy the whole pack if not necessary

Works well
these worked as expected and concealed the internal contents well. My only "beef" is that I only needed one but had to buy 12. The next time I might need one of these is several years away.

Emergency Purchase
These are just envelopes like the ones I buy for less than half the Staples price. I was in a rush and just grabbed them.

More than served the purpose. The self seal flap was sufficient although I always add an additional strip of tape.

Narrow envelopes
They were a fraction of an inch narrower than the items I am mailing. Couldn’t use them.

easy seal envelopes
the item works great if you don't have any prongs to close and tape over the item is complete sealed.

Customer Service from Skylar
Hi I’d like to mention that Skylar at the Staples Print Shop in Seacliff Village was very friendly and helpful. She took the time to make sure my prints came out right. Keep up the good work!

Wish it were cheaper but works well
I wanted a big envelope to put in a big card and I didn’t want it to be that orangey brown Manila envelope. I wanted something nicer so this worked perfectly.

Seal strip nice touch
Not the old weight of paper but nothing is the same quality these days. Zeal strip makes them easy to use.
