I discovered Vinylux nail polish in Miami this winter - it's a weekly polish that you can remove by yourself and doesn't require soaking in acetone or breaking the surface before. It lasts about a week nice and shiny without chipping and even longer on your toes.
I was very happy to find it here in London as well. I love red nails on me but they normally last only about a day. I'm not good at maintaining anything (hair, nails etc.) and I hate the idea of not being able to remove the polish by myself, so Vinylux is clearly the product for me.
