Hi Bill, ONLY BILL? I responded didn't I?
I'm not all that surprised that you haven't seen them at the LHS. From what I can determine, they're only available in certain markets, which don't include Canada or North America. Wrong-I can order them if I want them
Possibly the labelling regulations have something to do with that, as the only English on the labels is the brand name, colour name and Tamiya's address. Wrong again- That garbage they pull in the U.K. The U.S. doesn't prohibit foriegn languages on products(or stick you with a VAT either)
We've had them in LHS's here in Australia for over 20 years, so someone must be buying them, but as I mentioned above, I've rarely seen them discussed.
