I've had the envelope shipping method too. Luckily mine was ok then. That sucks about your Wolverine.
To be fair, the seller did pack it quite well and with more than enough padding (and as I mentioned, I'm not blaming him) and whatever pierced through the box would have done so in almost any packaging - it poked in probably about 6 or 7cm.
Oh, Metroplex wasn't sealed originally.
I bought him as opened, with all the contents being mint and look to have been used very rarely, if at all. Stickers unapplied, etc.
