Seriously! I was carrying the 2 snowtroopers around this afternoon from one room to another while wearing shorts - it's 110 outside - and one of the cards swung into the back of my knee, cutting it open about half an inch! Luckily it was a shallow cut, but I can't even remember ever having a cut back there before, it hurts pretty bad and is going to be hard to heal with it being a pretty sweaty area. Anyway, I was really surprised that these cards cut me, through a bag no less! The problem seems to be that the slightly thinner cardstock doesn't go well with the myriad of sharp corners designed into the card. That area in the back of the knee bleeds more than I expected, too.
