Want to talk about being rough on nails? This Jamberry mani has withstood burpees, push-ups, sparring, dishes and hours of typing. Day 9 looks just as fabulous as Day 1. Layering clear ColourCure on top of these nail wraps makes them nearly invincible. The only reason I am changing them out is because my new growth is messing with my OCD. ColourCure is beyond fabulous, easy to use by itself, with nail wraps or on top of lacquer. Add the fact that it is free of 8 harmful chemicals, vegan and cruelty free...it is a no brainer. What questions do you have? Ask me!!
