Crystal glass nail file

I don't really take care of my nails; I just trim them with clippers when they grow out. I dislike having long nails and find them extremely uncomfortable. That is why I don't bother getting professional manicures... but I happened to buy this product at a beauty expo.

The back of the file is made of crystal or glass material, and if you just rub it against your nails a few times, they start to shine and sparkle. I really like how easy it is to take care of my nails. Since it holds up pretty well, I use it often.
