Phoenix Aurora is a color shifting shimmer and glitter effect top coat, meant for layering over other polishes. Phoenix Aurora is the Mythological counterpart to Aurora Australis, containing the same iridescent glitter that shifts orange through gold and green, with the addition of the same color shifting pigment used in all of Starlight and Sparkles' Phoenix polishes, which shifts from red to gold to green, and flashes vivid red and bright green at the extremes of its color range. 

Rather than offering sets, purchasing four or more bottles of polish from the Mythological line in a single order will give a discount of 3.5% on all Mythological polishes in the order, which will be reflected in the cart under the line "Mythological line discount."

The last photo shows what Starlight Polish 15mL and 7.5mL bottles look like.

This polish contains "unicorn pee" pigment. The red to green color shifting pigment in the Phoenix polishes is the same kind of pigment that's in the original elusive unicorn pee polishes (Clarins 230, Liquid Euphoria Bliss, etc).
