12!  wow I'm set for life!
Just found out about glass nail files, these are pretty decent, the black one has a mirror finish, very useful.<br />They each came with their own separate hard plastic case. easy to carry in a pocket. 12 for this price I thought was really great but I don't know anything bout them, like I said I just found out about this kind of file.  They work really well on my Chihuahua too  haha!  She has her own now.
