Today's challenge is your oldest untried. This is mine. It is Sephora by OPI 212-Sephora. I don't know what took me so long to try this one. I think I've had it for over a year, plastic wrap still on it! It is a very dark brownish olive color with holo glitters and orange/green flakes. It has some shimmery glass flecks too. It is just a mix of everything!
