These envelopes are perfect... the size, double window work well for both checks and invoices. Quality& price means I won’t ever buy envelopes at an office supply store again.

These envelopes work great for my billing. They used to carry them in the store, but then stopped. I'm very glad I'm able to purchase the online still.

Why buy 100 at this price elsewhere, When you can get 500 for the same price at Sam's Club... AND HAVE THEM DELIVERED FOR FREE!!!! Quality is fantastic. This is a GREAT deal. Thanks Sam's Club!!!!!

Envelopes are good price, ok quality, but the return window is too low on the envelope, top line of return address was covered. Using company program that would not let me adjust the placement of address. Returned them.

We have been buying these envelopes for years & this last 2 boxes have been VERY ineffective. Every one has to be secured with tape as the glue does not hold the flap securely.

These window envelopes fit our QuickBook checks perfectly. I appreciate the 500 quantity carton. The adhesive seal makes for a quick assembly for mail.

They are good envelopes for the price, but every second or third envelope has glue in the inside corner that keeps the invoice from fitting properly. I have to mail 600 invoices monthly and the time to unstick each corner takes time.

These are the perfect for our company checks.

We have used this envelope for several years, would not buy any other

Good values, windows are placed a bit high compared to other #9 envelopes I have purchased
