Cartridges Smashed

I would keep a close eye on if it's still working as it should.
If the boxes are undamaged the cartridges were likely cracked before being put in the boxes, so the insulin might have been 'opened' for some time. Or maybe it has been frozen at some point and the cartridges cracked like a forgotten beer bottle in the freezer.
If the insulin turns out not to work anymore, do you have a way of obtaining new insulin where you are?
Good luck and happy holidays, hope the insulin is just fine and you still have enough of it!
