Two things I got my mom for her birthday this year were a Butter London nail polish and a pedicure. I had never tried this brand for myself (even as a nail polish enthusiast), but decided to throw in the towel anyway, because of the raving reviews it's gotten from everyone who has tried it.
The verdict? This polish is amazing. I can't speak too much on it's tendency to chip on fingernails, but my mom, having had it on her toes for a full week and a half, said that there have been no chips thus far. And even after removing it, she didn't get the yellow tint on her nails that usually comes with other polishes. As for application, I'm not sure if it's because we had just cooked dinner, but as I was painting my mom's nails, I didn't notice any strong polish fumes at all.
My first experience with Butter London was a great one. It's fume-less, smooth application, and long-lasting nature calls for an A+ in my book.
