Review: Perfect for Quicken, Excellent Quality, Hides Everything It Should - These envelopes are excellent quality, 24 lb paper. The Quicken checks fit in there perfectly, and the window covers everything but the return address on the check and the address of the vendor that is printed on the check. The listing kept talking about Quickbooks checks, but I should make it crystal clear that Quicken checks work perfectly as well. I had some concern that one could play with the envelope a bit to peek at what the amount of the check was, or the memo line, but no. The envelope shields what is inside, and you can't (at least I couldn't) bend or twist the envelope to try to see other information through the windows. This was exactly, exactly what I wanted, and although it is going to take me a while to burn through 500 of them, the convenience is worth it and the price was good. Similar envelopes that I found at the big box office supply store were $45 for 500. $45!!!!!! Insanity. And I think those ones weren't self-seal. These are very-very high quality, at a much more manageable price.
Review: Ideal for Payroll - Wow! I have bought more paycheck windowed envelopes in my work lifetime than I care to admit. These actually work when you peel and stick them because the adhesive glue is good quality. None of the windows are brittle, foggy, or tear easily. The price point is fair for the quality of product. I will order again if they do not raise the price significantly, 500 count for $30 is very fair pricing. I've gotten much more expensive envelopes from the big blue Q supplier that were not this nice.
