I bought a 15ml bottle of Indian sandalwood oil 5yrs ago, and it cost me S$50. It has a 'salty' tinge to the smell, unlike the 'sweet' smell from Indonesian sandalwood oil. But still, it beats what's coming out of India these days - atrocious foul smelling stuff. I wonder what they put in the oil...
I've been using the oil extremely sparingly, on one keris only.
