Nail Buffersx
There are 3 nail files in this group.  They work well. My only purpose for them is when my gel nail polish wears off and I have to strip the rest off for it gets caught in my hair, it leaves my nails rough and kinda bumpy.  So I really needed a buffer and these do indeed do their job.  The one file with the fading blue on it....that one is I think ..... Glass?  It has a nice feel to it and seemed to shape my nail as well, but I will stick to the buffers.
