Paid extra to get the envelopes that don't need to be moistened. They were supposed to be sticky - you peel off the tape and press to seal - but the glue was not sticky. I had to tape them shut. I also thought it was strange that the box was not sealed in any way. Someone could have taken some of the envelopes out and stolen them. I opened the box before buying and it looked full. Other than those two problems the envelopes were fine.
