Ouch! You be broke.
This is why I use ITW buckles and not National Molding's. This is from my friend's bag. Granted, this buckle was made four years ago and was used daily...but still, I've had a few of these buckles break on an old JanSport bag of mine.
Though, I'll probably have an ITW buckle break one of these days and I'll look like a dick.
