Off-White Curved Double-sided Nail File 100/180Grits is the perfect level of grit for shaping and smoothing nails! The larger grit side works wonders for filing off old material and the other side is great for filing down natural nails and shaping tips. Nice sturdy nail files allows you to shape your acrylic nails from square to coffin, ballerina, stiletto or any other shapes you want. The curved design makes it easier to get around cuticle and side walls when needed.
