It’s always a pleasure to shop at Staples. The employees are always friendly and helpful when
needed. The product is okay, the easy close strip
Is always good. My intention was to also get the
security one along with the strip for closure all in
one.

AMAZING Envelopes!!
These are the most incredible envelopes I have ever purchased! So WHITE. And the QuickStrip EasyClose Self Seal is so EASY, it's just the bee's knees. I have never been so happy about a purchase as I have about these wonderful envelopes. Thank goodness Staples requested this review, or I would never have had the opportunity to gush about these beautiful envelopes.

Be wary. It doesn’t seal.
Pre sealing feature doesn’t work very well.

Though the envelopes were in good shape, they were not very self-stick. I had to tape them to keep them shut.

Envelopes don’t hold up
Received complaints about envelopes opening up in transit, then saw it myself when a mailing was returned to me. Seals on the sides had blown open, causing the top to also open up (seal seemed to hold on the top though). Will not use these any further and will not buy again

Consistent Quality—Manufacture and Use
Over the years, I have used many boxes of these envelopes. I have never found a defective one. The self-sealing feature has always worked as advertised and so has resulted in a more consistent than the typical “lick and stick” variety.

Very Poor Product
The adhesive strip is pathetic. Will not hold the flap shut - need to use tape to close the letter.
It is also not completely across the flap. These are cheap and not worth it.

Very satisfactory business envelopes #10
The envelopes are of good stock. The quickstrip closure works well: no licking needed! Simply a good, useful product that does what it should.
