If you're doing your nails you need a base and top coat... so this is perfect as it's 2 in 1! I always have my toes painted and they last generally 4 weeks. I apply 1 coat of this, 2 coats of OPI colour and then 1 more coat of this. They stay shiny and don't chip. It's that easy! I never have my hands done so can't say how well or long it would last on finger nails.
