Citadel Layer paints are high-quality acrylic paints that offer a huge range of colors and shades to choose from when painting your miniatures. They are designed to be used directly over Citadel Base paints (and between each other) without any mixing. By using several layers, you can create a rich, natural finish on your models that looks great on the battlefield. All paints are non-toxic, water-based acrylics and are designed for use on plastic, metal, and resin Citadel miniatures. Each container contains 12ml of layer paint.
