This nail polish is unique in that it is extremely long lasting. As I applied the polish in a rush, I did not have time for base and top coats, so I just applied 2 coats of the product. My nail polish lasted 11 days!!! In between, I had to work with thinners (a project we were working on), and a tiny bit of the varnish came off, but not even enough to need to take it all off and reapply! Only a slight touch-up was required. I was amazed. This is a really great varnish, as it does not chip easily, and is low maintenance.
