The solid self-leveling base is incredible for smoothing out imperfections on the nail plate. With a thinner viscosity, this rubber/elastic base allows you to apply faster, working time of 3-5 seconds and a perfect and even application. This base is elastic enough to allow the nail to "move" and strong enough to protect the nail from breakage.
Additionally, you can use it as a base coat for any hard gel from the Zer.0 collection. The Primer-A-Free is necessary to secure the nail and protect it from the acid adhesion of this base
