The glass nail file is made of a float glass.  The technology of the production ensures that the filing surface is created right out of the glass nail file body and the surface is finely and uniformly roughened.  It is the delicate etching of the file that makes it safe and healthy for your nails.  Treatment with the glass nail file is very gentle, filing is effective and leaves a smooth polished finish on the end of the nail.  Regular use of the glass nail file helps to prevent nail chipping, peeling and cracking.  The etching in the file will never wear down and is not porous; therefore they cannot absorb water and form an environment for germs to multiply.

The finger nail file may be used in any direction.  It is very gentle and will not rip and tear at the nails.  Simply run the file under warm tap water to clean off the edging in the glass.  Store your file in its sheath and keep in a safe location.  Remember it is made of glass, although it is a tempered glass, it still can be broken.  Each file comes in plastic sheath.
