Comments about Quill Brand� Standard Single Window Security Envelopes; #10, 500/Box:
I was planning to use these for monthly billing; however, when I ran them through the printer for postage and return address, the windows MELTED!!!! I would have really appreciated knowing ahead of time, before buying these and possibly ruining my expensive laser printer that they are NOT compatible and should not be put in a laser printer.
Bottom Line No, I would not recommend this to a friend
