Ruby Wing, the first collection from SolarClub, is every free spirit’s dream: nail polish that changes color in the sunlight or daylight. Color changing polish has traditionally been unpredictable. But after years of research and development, SolarClub has perfected the most consistent, stable, and durable SolarActive® technology to date. Formulated and bottled in New York City, every Ruby Wing™ polish is completely non-toxic, environmentally safe, and 4-FREE (no harsh chemicals like toluene, formaldehyde, camphor, and DBP). Plus, they're vegan, and never tested on animals. Your life is full of variety and change. Shouldn't your nail polish be, too?
