  - 040102316 (Toothbrush using loess and gold)
* Approved by U.S. Food and Drug Administration (FDA)

• An extraordinarily remarkable double-bristled toothbrush, incorporating nano-sized gold and loess particles. This brush provides the sedative, antidotal and purifying effects that are the unique powers of gold.
• Unlike conventional toothbrushes, this toothbrush is made in a double-structure consisting of normal bristles and fine bristles, so that plaque on the teeth and food remnants in between the teeth can be removed completely. With fine bristles that massage the gums while brushing, it is especially beneficial to those with frail gums.
• Dentally designed handles, with double-projected natural rubber grip and brush head, are designed to suit the oral structure.
• Compact sized brush head delivers thorough removing of food remnants from behind the molars.
