A thin viscosity gel that gives your nails a super strength flexible bond. Need your nails to last longer than with Base N' Gloss, this is the gel to use. Some customers may have problems with adhesion, by using Opti-Bond you help this problem. Tip; brush on Affixit first for the strongest bond (please note, it will be much harder to soak off when doing this combination). Opti-bond can also be used with Classic Gels.
