I spotted these in Farmers Yesterday. The display says that this mini four piece collection is called "It's all about the color", but Google doesn't tell us anything much at all about this collection.
Left to Right: A Million Sparkles, A Lit-teal bit of Love, Vio-lets Talk About Red, Shoot for the Maroon.
Nicole by OPI retails for $19.99 at Farmers and some pharmacies (usually Life pharmacies).
Lots of Love
