I added Color Club Revvvolution to HC Sky a few days later.
Revvv looks like a dud, but I swear it's not. These are just terrible pictures, but they are the only ones I have. For those who have no idea what I'm talking about, Revvvolution is a black/charcoal holographic polish. Unfortunately, there have been "duds" emerging recently, most notably with the Color Club holos. Some say the holo pigment is becoming more rare and therefore more expensive. Lucky for me, none of my CC holos are duds.
