Professional file with two different grains

High quality special file with two different grains to professionally shorten and shape the nails. Unlike other files, tiny crystals are worked into the latex surface rather than sprayed onto it.   This technology means that the grinding particles move back into the latex bed when filing, which makes filing gentler and more even.Thanks to the flexible core, the file adapts perfectly to the nail contours, which reduces the stress on the nails.
