Re: the first part - yeah that's my worry. Like, in the vast majority of cases, it'd probably not be a huge deal...but then there'd be that one time where someone breaks something while tugging on the case to get it out, lol.

Re: the second part - oh interesting. Is that something you can get from USPS or UPS? Or just buy it on Amazon? I searched there and found this, is that basically what you're referring to?

Thanks!
