Tiki pendant

Bought this tiki pendant online, but the seller did not know who made it.
Can anybody help out?? (added the teeth after buying it)

Apparently the seller bought at some tiki event some years ago.

Can you post a picture of the back of it? To me it looks like it was made out of a mug. Maybe it broke in such a way it was able to be salvaged and turned into the pendant.

Aha..I see! I can post a picture later, but its only white, with no glace.
