In short, it's a subscription service that you pay $18 a month for 3 designer nail polishes that you choose. You use them (they have a limit of 3 applications, but how are they going to monitor that?), return them, get a new box.
Here are the brands they have:
Dolce & Gabbana
Aaaand a few points from their FAQ that I think are important to point out:
Who would this be good for?
Those who don't frequently buy nail polish
Someone wanting to try out the top brands, but not pay $$$ for the polish
Someone wanting to try out specific colors before buying the polish
Soooo, what do you think? Still want to join? I think I'm going to stay away from this. I thought it was a subscription service similar to Julep. Boy was I wrong!
