There are several types of pigments I use to color toys, all of which are non-toxic and come in two forms: powdered pigments (usually mica) and specialized silicone pigments which have a paint-like consistency. Where possible, they are also cosmetic grade, meaning that the raw pigment is safe for contact with the human body even if it is not encapsulated, such as it is in my toys. Certain types of pigment, such as Glow in the Dark, are not specifically cosmetic grade, but they are safe nonetheless and are not radioactive. I do not use craft glitter in any of my products. Any references to 'glitter' are describing a type of larger-particle mica, rather than a plastic or metal flake material. See the FAQ section on shop terminology for more information on the specific types of pigments you might see in my products.
