good value for a finishing smoother set [SEP] this teenitor nail file and buffer gives you quite a bit of product at a good price this includes the large sided nail files as well as the soft sponge smoothing finishers these work well for either smoothing out the ridges on your natural nails or doing doing a final once over for a clean finish i would not be using these for the first pass on acrylics though as the grit is too fine this is a good value set
