We developed a new system to produce the nail polish gels as fast as possible to match up with the fast fashion’s pace. We also designed different kits for people based on their needs, for example, for starters, we understand the struggles of choosing what products to start with, therefore we picked the necessary items and combined into a Starter Kit which became many American girls’ first nail DIY kit. We have developed more than 700 different colors in a year, updated for every season, every holiday, and every occasion.
