Rachel Williams is a high school student who had been biting her fingernails since childhood, until the day she decided she wanted beautiful, healthy nails. Her grandma, Barbara Williams, gave her a rubber band and asked her to snap it each time she had the urge to bite her fingernails, and before she knew it, her nails started growing. It was not long before a manicure was her next reward. She was so excited she decided to write a book to help other teens grow their nails using Sammi Super Snapper as a tool.
