Add a touch of glamour to your artwork with the Kuretake-ZIG Wink of Luna Metallic Brush Pen. Its soft nylon brush tip lays down metallic color that looks great on both light and dark paper. It's filled with water-based, opaque pigment ink that's waterproof when dry. The squeezable barrel was uniquely designed to resemble a cosmetic product, but please don’t apply the ink to your skin (it looks so much better on paper anyway!). Before use, remove the black protective ring.
