One of my purchases in the States is this gorgeous nail polish from Sally Hansen - 450 Kook a Mango.
Although it doesn't come close to the color of a mango, it is a great warm, soft neon pink for spring. The neon level is just about right, it doesn't hurt my eyes.
What I love is that the brush is super wide. It's opaque and has a creme finish. Two coats and you're good to go!
For almost 15 ml you pay around $7.
What are your favorite spring colors?
