The line contains 5 full sized polishes and a mini polish set that contains 4 mini polishes.
The full sized nail polishes are $9 each. They come in the following shades:
Chic From Ears To Tail
A Definite Moust-Have
Innie Minnie Mightie Bow

The mini set is $12.95. It contains all of the same polishes with the exception of Minnie Style.
I have never tried OPI polishes but after seeing this collection I think it's time.
