Eric Young: Nice to not have to lick to stick the envelope shut. These are less expensive than others I’ve purchased from the office chain stores and seem to be of a higher quality.

CarolKbaum: These envelopes are a good quality. I especially liked the stickiness of the seals. I have used other brands before and the seals did not hold and I would have to add tape to make sure my checks made it through the mail. I will definitely order again!

Jonathan W. Lee: 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.
