A subscription based online nail polish club that allows women to try (or 'rent') luxury nail polish.
For $18 a month, women choose 3 luxury lacquer (average RRP $23). They use it for a month, send it back and swap it out for another 3. No longer need to buy lacquer and hoard half-empty bottles.
Nail polish is the fastest growing segment of the beauty market ($1B+) with 70% growth in 2012.
