Koa wood, very rare and hard to find....my dad used to squirrel that wood away for his bronze sculpture bases....at a certain point, I don't think they even allowed that wood to be exported. I know he switched to teak eventually, maybe it could be but the cost was $$$$ through the roof.....I could be wrong.....Since my car came from Hawaii and has the Koa wood trim the hula girl would be a sensible addition.
