These cards are made by wrapping printed paper around 2"x3" pieces of cardboard. I know this because one of my cards has the paper wrapping separating from the cardboard. It's not much of a problem because it'll be kept sleeved. Everything is glossy, except the background on the card fronts, which have a flat finish. The players are puffed out from the rest of the card. It gives these cards a nostalgic 3D quality. I don't think the cards themselves could be puffified (yeah, I'm making up words.), without making the card backs concave. Although I have seen cards with minor convex and concave lines on the front and back, I have not seen anything as dramatic as the entire player lifted out from the background. Nice.
