Ordering N during winter? Will the bottles freeze over?

[Trattkantarellen198]

I have tried searching in vain for an answer to this question. Does anyone know for CERTAIN that these bottles can handle cold? It can go to -30C / -22F in Sweden if I am unlucky.

I don't know the answer so bump

But make sure the N is real and not a scam
