Our holographic pigment powders are super fine micro flakes to be used on nails or in nail products. This holographic powder can be buffed on the nail to create a super linear holographic effect or added into nail polish/suspension base to create a more dispersed holographic effect. It is heat resistant, and non-soluble in solvents and water. Particle sizes come in 20, 35, 50, 80, and 165 microns. 165 micron is a true flake vs a powder. Container: 1g stackable jar by volume Particle size: 165 micron diameter, 1-2 microns thickness Ingredients: Aluminum coated PET Instructions: Add very small amounts and mix thoroughly before adding more. A little goes a long way.
