Amsterdam Glow In The Dark Medium 500ml contains phosphorescent pigments that, after being exposed to light, will glow! Great for use as a final layer over an acrylic painting, Glow In The Dark Medium works best over white paint and is waterproof when dry.
After use, utensils can simply be cleaned with water. Mixing Glow In The Dark medium with acrylic paints will reduce the glow effect.
