this review title is: glass nail files are not all the same and the content is: it took a while to find a quality glass nail file one that had a finely etched abrasive surface not this file this item has a rather rough surface and i am not sure that it is etched as opposed to presenting a secondary abrasive adhered to the glass so far the only file that meets my expectations is made by vaga it is the real thing as far as i can determine most of the low cost files are not acceptable nice little individual protective cases though.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
