As an entirely new addition to the OPI GelColor lineup, this gel base coat nail polish is a great product for clients with weaker nails to enjoy gel nail polish manicures. The added durability comes from a formula with a higher gel to solvent ratio, this means a thicker viscosity and a brush we’ve specifically designed for thin and precise applications. Plus, it's infused with calcium and vitamin complex, which leaves nails feeling stronger during gel nail polish wear. With up to 60% more strength to the natural nail overall! Because of its serious staying power, it’s ideal for clients who visit salons every 2-3 weeks.
