Yeah, you beat me to it. For context, from the article:

If you find pre-painted miniature figurines of any sort, it is basically 100% certain that they were painted by assembly-line workers at a factory in China. There’s a whole mini-industry dedicated to rapidly molding, producing, and painting toys and figurines designed by Western modelers, everything from gaming minis to Homestar Runner collector’s toys.
I’m not really judging, since I’ve got a closet full of Heroscape minis. Just something to be aware of. And, um, awesome article.
