I guess we can stop speculating about
GW shifting from metal to resin now...
The Citadel Finecast miniatures are all made from a unique resin formula. For us as hobbyists, this is great news. The resin is easy to work with and quick to cut off the sprue, making assembling a miniature easier than it has ever been. Not only that, but it's incredibly light too, which means pinning wings and other heavy components will be a thing of the past. So, quick and durable, that's a good start. But of course, one of the main reasons for this change to resin was quality. One thing you'll notice immediately when you pick them up is the exceptionally sharp detail on the model, which can only be described as staggering. For dedicated painters (which we all are to some extent) this is a dream come true.
