Review title is great files [SEP] If you have never tried a glass nail file do yourself a favor and try these out.  Even as A guy I love how these work on my nails.  They leave such a smooth finish to your nails and greatly reduced the number of hang nails I get.  My girls love these and use them exclusively for all their nail care needs.  These come packaged in a padded case so your assured a safe chip free  file.  These are super quality and should last a lifetime.
