From their announcement:
Hello, today our new range of plastic resin miniatures, WarCast, makes its debut. Here at AoW we are very excited with this new medium, as WarCast miniatures look and feel very much like plastic miniatures, but their detail definition is as good as "pure resin" miniatures.
The first four WarCast regiment boxes are now available for preorder exclusively at our online shop. As usual with our regiment boxes, the preorder edition will contain exclusive pieces only available during the preorder period.
Make sure to see pics and details of these new WarCast minaitures here.
