Butter LONDON's nail polish is superb. For starters, they do not contain Formaldehyde, Toluene, or DBP. The polish itself works really well too. It goes on smoothly and is long-lasting. The colors are to die for.For a VERY limited time, the brand is on sale at The Fairest for 50% off! Personally, I'm a fan of Crumpet, a beige color. Nothing is more classy than beige nails. Check it out!
