Comments about Quality Park� Reveal-N-Seal� Double Window Envelopes; #9, 500/Box:
The adhesive under the "Lift Here" flap is too strong. If you're not careful, it will partially tear the flap. The envelope will still be useable, but they need to un-childproof that main adhesive so that you can seal the envelope without ruining it. The last two boxes I've ordered have been this way. I will not be ordering anymore anytime soon.
Bottom Line No, I would not recommend this to a friend
