Sorry to hear that Sam - unfortunately, it's a budget release and so corners have been cut, leading to very poor packaging.
Amazon should replace them for you (even though it's not their fault), although it does mean the hassle of having to return the 6 damaged ones, with no guarantee that the replacements will be ok.
I managed to superglue mine, although had I'd purchased them rather than won them, I would have been less happy.
Time in solitary for whoever authorised such poor packaging is what is needed
