Makeup Nail Polishes Opi GelColor 15ml Inspired by the boundless energy and creativity of the world's metropolis, OPI's Tokyo Collection brings the multifaceted city to life in twelve new shades of colour. First, all GelColor products must be shaken for 60 seconds before use so that the ingredients can be optimally mixed. Apply a thin layer of the GelColor base coat as a base and cure for 30 seconds under the double-cure LED lamp - do not remove the dispersion film!
