These #9 envelopes (not for QuickBooks checks!) are also often used as reply or return envelopes in business mail. The #9 envelope size fits standard paper folded into thirds and also tucks inside #10 envelopes. Versatile, sturdy and inexpensive enough to use for budget-conscious bulk mailing, billing, brochure mailers, or to use at home as money envelopes for budgeting, coupon sorting and more. Our envelopes have a windowless front panel ideal for everyday uses — no need for rulers and precise window measurements as required for window envelopes. Each super white envelope is made of 24 lb white wove paper with side seams, leaving a smooth, uninterrupted front panel for labeling, printing or hand addressing. A simple gummed moisture-activated closure seals tight. Machine insertable for inexpensive customization: run our windowless envelopes through a laser or inkjet printer or professional bulk mail equipment. Ideal for business stationery, statements, legal papers, invoices and more. These bright white envelopes are perfect for all sorts of business applications. Stock up on these bulk boxes of 500 envelopes, great for high volume envelope users. Ideal for accountants, law offices, or any workplace or small business that moves large volumes of mail. #9 Envelope measures 3-7/8 x 8-7/8 inches. 500 Per box.

Unfortunately these envelopes where warped and did not have uniform thickness, possibly they might have been stored in a humid environment. The reason that this was an issue is because my office prints over a thousand envelopes monthly, and they jammed constantly in my printer which lead to it breaking.

good envelopes. Small, machinable flaps. Just what I needed.

I do mail-in sweepstakes. A LOT of mail-in sweepstakes and I need a lot of envelopes. I usually purchase #10 envelopes which are the full size "business" size. But sometimes when I find a good deal, I'll purchase other sizes. This was an excellent deal. Here's a hint for making purchases on Amazon. When you're searching for envelopes (or anything else) on the left side of your screen in all the options, you'll find an option where you can search for "New or Used." If you search using the "used" feature, you won't get actually used products, you'll get "scratch and dent" results if you get the meaning. The packaging will be damaged. The box these 500 envelopes came in was crushed in my case. The envelopes? Perfectly fine. So for $7.30 I got 500 envelopes instead of the full price. I'd highly recommend you look for "used" envelopes to score these deals!

This item is high quality and reasonable cost. I cannot even come close to this price at my local office supply stores. And delivery was quick and painless.

This is an envelope that fits in an envelope without resorting to a short envelope. I found they are as good of quality as what I have previously purchased elsewhere and the price was competitive. I use them to give my clients a return envelope when I submit invoices for my small business.
