Disappointed in these envelopes. The toner flakes off in my HP laser printer (doesn't do for other envelopes) so I have to put clear tape over the printed address and return address. Also the peel strips tear easily when you rip off to seal I mean they rip into smaller parts instead of peeling off all in one motion.
Many of the envelopes had problems getting the paper covering the flap glue. the paper would tear & not come off. Had to spend extra time trying to remove the paper so the envelope would seal. very time consuming for large mailings
