These envelopes are very budget-friendly, and the paper quality is not sturdy, but good enough.

This review is for: 5009 Double Window Security Envelopes, HERKKA No.9 Double Window Business Envelopes Designed for Quickbooks Invoices and Business Statements - Number 9 Size 3 7/8 Inch X 8 7/8 Inch - 24 LB - BlackThis says 24 pound, but they feel very thin. They are on the cheap side. Certainly not the worst I've used, but far from the best.The windows are larger than some other envelopes, but work for my billing invoices.They are pretty pricey considering alternatives.I hope this was helpful.

These are good quality business envelopes. The paper can't be seen through and the plastic windows are clear and are properly adhered to the surrounding paper, so they doesn't separate, and the self-sealing strips stick well and keep the envelopes closed.

I used these for saving money, not really for mailing but they are just as great as any other regular envelope. The adhesion works great and the box comes with so many.

No issues with this. All envelopes were clean usable and closed perfectly. Great for sending off letters. Especially if you know how to send a letter head to fit the windows. Even just to close up some documents for drop off. This is a great amount for a great value.

I inspected the envelopes when they arrived, and I am pleased with their quality. There is a divider for every 100 envelopes, making it easier to keep up with the quantity. The flap adhesion holds well, and the peel strip is on well (unlike others whose strips barely stay on, making the envelopes stick together.) I tested the security markings inside, and it works well to hide details of the contents inside. This was a very good purchase and worth buying. I would get them again.

These are exactly as envelopes should be, if a little on the thin side. I kind of expected that for the price and it hasn't been an issue for me at all.

These offer very good privacy. I wrote with thick black marker and you can't see it from the outside. The seal is very good. No gaps. Minus one star because they are very thin and cheap feeling.

We had been using the same envelopes for checks and for QB statements and invoices. I assumed if it worked for one, it would be good for the other. Bad assumption.
