Review (1/5): NOT a nail buffer - this is a file - worth maybe $8 so way over-priced
A nail buffer requires a very, very, very fine grit so it will polish and shine the nail. This supposed buffer is medium grit, which means it is good for filing nail edges and maybe ok for removing ridges from the nail surface if you use very light pressure, but it will not polish the nail top surface - i.e. despite the name, this is a file. When used on the nail top surface, it mostly produces scratches. Even if the grit on this file was fine enough, it is too wide to properly polish the small curved surface of a nail (I am not talking thickness/height here, I mean width). Plus decorative top is just glued on. I have tried so many glass nail buffers that I have lost count - all were too wide and too coarse to actually buff the nail except one - the one that actually had a fine enough grit was so wide that it could only polish my nails in spots. I would love a long-lasting glass nail buffer, but at this point my conclusion is that glass is not suitable for buffing because it is too rigid and all supposed glass buffers available are very badly designed. I give up. I guess I will continue with disposable 4-sided soft block buffers - at least those work properly. Gave the file to my niece as she loves the appearance of it and it is good for filing (properly etched, medium grit), just way over-priced at $13 and NOT as described.
