I am using these envelopes to solicit donations for Fred's Team. Like the pull-strip to seal so you don't have to lick especially since I am sending a lot. No cons noted.
I love that these envelopes are pull and seal. No more licking - YUCK! They keep inportant documents safe from the viewing eye. The only thing I don't like is that the self seal doesn't go far enough over to the ends so the whole envelope is sealed. I end up using tape to cover the whole flap just to be sure. But I love them otherwise.
