I have better luck with the padded ones...and those are the only ones I use anymore.
I did receive a padded envelope from one of the sellers and it arrived all torn up on the outside...I was afraid that my magazines inside would be torn, but they were just fine.
I did a little test and tore the entire paper off the padded envelope to see what was left. It's actually a bubble bag fully protecting your item. So even though the outside paper had been torn, the bubble bag stayed in tact and my magazines didn't get a scratch on them.
