I can tell you, they're painted in a smooth matte finish. They have a nice weight to them and very nice detail. They're similar in size to Skylanders, some being as tall as the Giants figures.
When fist announced, I was honestly very concerned they would look like McDonald's Happy Meal toys, was I wrong!
In my (admit-tingly biased) opinion, they look and feel like collectible figurines you'd want to have on your desk at work.
