Comfort builder gel is a modeling gel with the consistency of a thick base and in incredibly beautiful colors. It is a hard and durable material with a very comfortable consistency that quickly self-levels. This line of gels is suitable both for modeling and for strengthening the nail plate. We recommend applying the Comfort builder gel on a base made of a transparent base, both the Universal NailApex base and the Light base are perfect. Preparation of the nail plate is standard (choice of degreaser and ultrabond/primer).
