These Envelopes Poorly Seal
We have to tape these closed. This defeats the purpose.

Too small
These envelopes were too small for two pieces of paper. The quality was awful…thin and not sturdy at all. Would not recommend.

They do not seal properly
The glue they use to seal the envelopes is terrible. Doesn't keep the envelopes sealed. Have to use scotch tape to keep them sealed.

Not impressed
Expensive envelopes with windows that do not fit QuickBooks checks nearly as well as the Staples version, which was out of stock. Will not order again.

Don't buy these envelopes
These envelopes are too small. It is IMPOSSIBLE to close and seal the flap, even when standard 8.5 X 11 paper is folded perfectly into thirds.

The quality of the envelopes is to poor. The window didn't cover important information. The paper of the envelope is to thin. They are not what I was expecting

Windows not quite right for Quick Books checks
I ordered these because it stated that these envelopes work for QuickBook checks. The windows aren't quite right for my QuickBooks checks. The memo line shows up in the address window and the entire "from" address doesn't show up in the top window.

Perfect envelopes for QB voucher checks
I only bought these because they were on sale. A QB voucher check fits in them perfectly. I really like the easy close and seal, no licking!
I would recommend these #8-5/8 double window envelopes.

seal strip is smaller/seems ok
This was not my first purchase of this envelope but when asked to review, I compared the last envelope to this one that was just received. The seal strip is smaller. It appears that it will hold ok but can not say if it will stay sealed or not over time.

Fits QuickBooks Voucher Checks Well
My 3 part voucher checks fit really well. Only drawback is if we enclosed more than one additional sheet of paper they are hard to stuff but for 99% of my checks they are superior!
