Caren Original Ruby Crystal Stone File;

Ruby crystal stone nail file - this revolutionary nail file is like no other file you have ever used. Thousands of synthetic ruby crystals are bonded together to form a unique stone surface for filing and shaping nails. Filing in both directions (unlike traditional nail files that weaken nails and cause microscopic cuts), the dust from the ruby crystal file embeds in the nail edge to help prevent splitting and strengthen the nail as it grows. Use with the other ruby crystal nail care products for healthy, natural, nails you do at home without the expense and damaging effects of acrylics.
