As a female rock climber who also loves to paint her nails, I am always on the hunt for a good long-lasting nail polish. I am honestly amazed by the staying power of these polishes. I have climbed with this nail polish on, and my nails stay looking the same before and after I climb, which is amazing! I have never had a nail polish not chip from a climbing session until now. Also, I would like to add that the formula doesn't come out streaky, dries quickly, and application is easy with these brushes. After a week or so, despite not chipping the polish does lose a bit of its shine, though it's very subtle. Highly recommend!
