Comments about TOPS W-2 Tax Form Envelopes; Gummed, 100 Pack:
I printed employee W2s on perforated 4-up forms; when folded in half and placed in envelope, the sender/recipient addresses didn't match up with the windows on the envelope. Had to print stickers to go over the top of the window so it would reach employee in the mail and wouldn't disclose personal/confidential information.
Some envelopes came out of the package already sealed shut; couldn't get them open without ripping the envelope so they were wasted.
Bottom Line No, I would not recommend this to a friend
