(UPDATED from 4 to 5 STARS at bottom of info) Affordable, seal adheres well, medium thickness I'd say. Feels like my items can be safely shipped with bubble wrap. Bright color and neat design. My only complaint is that many of them are a little dented at the flap, which means I have to tape them shut to keep them from snagging on machines at the post office. UPDATE 01/25/2019. I've ordered a few more times and no creases on the valve, it must have just been a slightly erroneous order. These envelopes seem a little thicker to me than before, OR maybe it's because I use other email programs and they don't seem as strong/thick as these. If you are looking for something with a decent thickness that is still light but portable, with a nice design for men or women, great seals and not too expensive. THIS IS THE BEST I FOUND! I would love to find a way to find more designs in this envelope (and be sure they are of the same quality). I can't figure out how.
