Quality Park® Redi-Seal™ Double-Window Security Envelopes, #9, 3 7/8" x 8 7/8", White, Box Of 500

It was exactly what I ordered and wanted. The package arrived on time, and in excellent condition. Thank you!

Great double window security envelopes...especially liked the way they easily self-sealed. Another bonus is that the envelopes fit my invoices printed from QuickBooks perfectly!

I used the smaller size for payroll checks and had difficulty with the tabs when inserting checks. The size 9 is larger, but the checks go into the envelopes much easier and faster.

No licking envelopes is the best part

This was the perfect fit for my documents

Great price and quality. Saved my office $$ and time with theses self seal envelopes.

cheaper price than what I had been paying and quality is acceptable.

I like the size of the envelope. Other one's I have purchased in the past, I would have to fold invoices smaller to show names through windows & be able to close. These just the normal fold & no problems with closing. I use for checks also & no problems.

Easy sealing with no extra paper waste.

When I had ordered these, i had been under the impression that they are exactly like the #9 ones, however the back side of them is not. You have to keep the sticky-ness of the envelope away fro the papers or else it sticks and rips everything. Very annoying and very frustrating.
