Rubber Base is a rubber base designed mainly for problematic nails on which a hard base does not stick. Significantly increases the adhesion of the gel/varnish to the nail bed. Thanks to its unique consistency, the base does not run and at the same time adjusts to the nails and creates perfect bright lines. You can use Rubber Base as a base for a hybrid or to create the structure and color of a natural nail. It lasts up to 4 weeks on the nails.
