#9 Standard Invoice Double Window Secur
on August 1, 2009

This product is used for invoice mailings. It seems a little on the high side for price but is comparable to other office suppliers. Unused envelopes tend to stick in humid surroundings.

Windows are too high for my use.

I had some when I took over the job and tried to replace the envelopes with Staples - have not found a quality envelope the size I need. I tried a different version and they were worse. I guess I'll have to buy the next box some where else.

What a nightmare.

I'm serious this is crazy. I have 300 of these envelopes sitting on my desk stuffed and ready to be mailed and they won't seal. At all. The gum is the next best thing to worthless and I've taken to sealing three at a time and then sticking a heavy book on it for an hour. What's more the envelopes themselves are of shoddy construction -- more than one of them has completely come apart as I've been stuffing them. I am NOT PLEASED. What a waste of money.

Our office goes thru a lot of these envelopes and the person using them is pretty particular!
