There are two types of Glitter Gal Holographic range of colors.
Glitter Gal Australia “holographic” range – this range is a true linear holographic finish
They use small holographic particles which gives a perfect hologram and linear effect.
Glitter Gal Australia “sparkle” range – this is a true sparkle finish
They are using large holographic particles which gives the appearance of a glittery effect though uniquely smooth.
Which really the only difference between these two ranges is only in the finished appearance and size of holographic particles.
