Holographic glitter, also name as laser glitter, is formed by holographic film treated by vacuum plating, high temperature coloring and machinery precise cutting in order.
In fact, there is a big difference between holo glitter and polyester glitter. There is a micro embossed metallized polyester film, which used to precision cut into Glitter Flakes. The Holographic reflection is obtained by the reflection of light giving a kind of changing colour effect to the glitter.
