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.
