New from Hand & Nail Harmony comes Gelish Color Gels. The gels apply like polish, with twist cap and applicator, but are cured in a lamp like gels. The gels come in an array of colors, and cure in a LED lamp in 30 seconds and in two minutes in traditional UV lamps. Gelish stays on nails for three weeks with no chipping or peeling, and soak completely off in only 15 minutes.
