Query: RELIABLE PRODUCT - RELIABLE COMPANY

In the large number of envelopes we've orderd over the years there has not been one with a flaw. We rhink that's pretty good for an item that is undoubtedly mass produced. Obviously, we're well pleased with the product as we continue to order.Also, obviously we have not always done business with this company - wish we'd known about them sooner. Their service is prompt (a confirmation of order within 24 hours along with UPS tracking number). The envelopes are always well boxed so they arrive undamaged. Couldn't ask for more.We recommend both the envelopes and the company.
