Good nail file but...
So glass nail files are nice.  I've bought a few of them.  They do a better job of filing than metal ones and they don't wear out like the standard paper grit ones...usually.  I have purchased cheap ones in the past that the grit must have been painted on the glass and there were obvious wear patterns.  However, this one is nice, and while it is more expensive than a standard nail file, it will last a long time.  The only negative I have with this is the pictures shown.  There is a before and after use picture of nails looking very shiny....that ain't happening.  This is not a polishing file, it will not shine your nails.
