ONLY WHITE CNI Poly Gels Nail Up. The second step in the NailUp system. Polygel Only White - extremely white, has the highest consistency density. Suitable for creating a French design in modeling or as a monochromatic base for manicure. Polygel is a hybrid material that incorporates the best properties of gel and acrylic. The polygel keeps its shape and does not polymerize without UV light, so you can work with it for a long time, bringing the shape of the nail to the ideal leveling, and this will significantly reduce the filing time. Fileing a polygel is as easy as filing a gel. It is not too hard and can be easily removed with nail files or cutters for manicure.
