The coarse 100-grit nail file has been designed for hard gel and nail extension products -primarily to shape and shorten nails by effectively filing down thicker materials such as BIAB™, ProForm™, GelPot and other hard gels. You can also de-bulk and remove gel product with this lower grit file, making it the perfect choice for nail techs working with artificial enhancements. It is not recommended to use this grit on natural nails as it is too coarse and abrasive. For natural nail shaping and prep, use the 220/240 Half Moon Nail File.
