It was the only good fit for Laser Checks (the ones that are one per page). A little pricey though but I guess that is the market price for them as it was a little less than the bank offer.
Window envelopes from previous supplier were significantly more expensive but of very similar quality and these fit the openings I need for my checks. Good value for dollars spent.
Filled our need for a QuickBooks Laser Check mailing window envelope where the windows align perfectly with the return address and mailing address. Works well for both Payroll and A/P Checks.
