Review (4/5): Stylish, nice colors and functional nail files!
These nail files are really nice, stylish, colors are super cute and each nail file comes with its own hard case.
Material is soft, curve and sparkling on one side and "rough" on the other side. The nano glass side is gentle enough for your nails.
You can polish, buffer or just trim your nails and will have great results. It is highly recommended to rinse your nail files after each use, warm water (a bit of soap if desire) will do the trick.
The only reason I am giving it 4 stars is because they are too thick that it is difficult to use it when trying to file your nail from the bottom.
