They were. They split apart and are now fighting, it appears.
I'm in the US, and the Gravity Colors I've always ordered, before the split, came in plastic bottles. I think its an exaggeration on Antonio's part to call the U.S. paint counterfeit.
I've talked to the U.S. guy, and he was upset at the Euro division. His side of the story: he was upset that the euro division wasn't being helpful or communicative. He couldn't get custom colors his customers wanted. I once waited four months, and he finally said the Euro division wouldn't deliver the custom colors I had ordered.
