Have sandal-ready feet in no time! Our Bacteria Shield Glass Foot Buffer is coated with a patented Anti-Bacterial Finish, this non-absorbent glass foot buffer resists bacteria, so that it stays clean and hygienic. Use the rough side to target thick skin and callouses around the sole and heel. The smooth side can be used to buff and soften skin as a finishing touch. It can also be used to file toenails and is suitable for sensitive skin and nails. After use, it can be placed under sunlight or UV light for 2 hours to self-clean. The premium-quality glass is made to last and is fully recyclable.
