I live and die by this nail polish. I not only use it on my nails and toes, but I also use it on my daughter's. She's significantly harder on her nails and toes than I am, with the vast majority of the polishes I use on her only lasting a couple hours a day if I'm lucky. But I bought her the entire Crayola collection when it came out, and they are some of the most durable, long-lasting, vibrant polishes I've ever used in my life. Most of them only need one coat, two if you're using the lighter colors, and they wear like iron.
