Second, mammoth ivory is a kind of ivory, and it is sensitive to the law at present. Although it can be legally traded, there must be an inspection certificate issued by an authoritative organization to prove that mammoth ivory is sent, not modern ivory.

So to sum up, of course, the goods can be in good condition, but the procedures are complicated and the cost is not small.
