This is one of the over-priced blanks from eBay.  While I think the blank is interesting, I have a feeling that we will see these mass-produced by Taiwan in a matter of a few weeks or months.  The blanks were significantly heavier than normal polyester resin which I attribute to the significant amount of metal powder in them.  Other than that, they turn like plastic, smell like plastic, polish like plastic and look like plastic.  While I like the finished product, I'm not "blown away".
Thanks for your always generous comments. [8D]
