Endangered as Brand: Why is ivory still being "sold"?

Then I came upon the Grooming Lounge Ivory Shave Brush. Do they mean real ivory? I doubt it. I hope not. At $70, probably not. (These brushes range from $12-150 and $70 is high average for any type of handle.) Most of the other white handled brushes say imitation ivory in one form or another. This one just said ivory. Why?
