Transform rough, cracked heels with the Scholl Nano Glass Foot File. This next-generation solution for smooth, touchable feet is powered by advanced nano technology. It gently buffs away hard, callused skin with precision and ease. The even distribution of exfoliation points and nano-level grinding surface deliver noticeably smoother results than traditional files, without harsh scraping. The file is gentle, durable, and easy to use. It's safe for sensitive areas and comfortable to use. The file is also reusable, washable, and portable, making it ideal for daily use and travel. To use, soak your feet in warm water and pat dry. Gently rub the file over rough areas, then rinse or towel away dead skin. Finish with your favourite foot cream to prevent hard skin from returning.
