This system was designed by medical nail care professionals to work with ELON Nail Conditioner to rebuild and restore the original health and beauty of nails. All ELON Professional Nail Care System files are fully padded for comfort and durability. ELON Professional Nail Care System files can be sterilized for any health care concerns which may arise. They are the finest files available today. By using the ELON Professional Nail Care System along with the ELON Nail Conditioner, you will discover the ability to provide a beauty and shine to natural nails without the use of polishes. Polishes tend to block some of this action and nail polish removers (by large content of alcohol) rob the nail of moisture. Discover a healthier alternative to lustrous nails.
