 
	came across these in a few places in China ...... they seem to cost from a couple of dollars to a few hundred dollars for a pair
forgot to ask the vendors while I was there so checking with anyone who knows a little information on these ?
are they natural or carved ? what are they used for ? or just only for display ? etc etc
thanks for any advise
curious
