You’re probably already familiar with the **VBO Premium Toothbrush** with **black quartz bristles**, right? Are you curious about why this toothbrush is manufactured in Japan?

Black Quartz is Mined Exclusively in Japan
Black quartz is an ore found **only on the island of Hokkaido, Japan**, and nowhere else in the world. It forms through the **fossilization of marine algae**, which accumulate silica in their cell walls.
Because of its **black quartz infusion**, the bristles of the **VBO toothbrush** have a rough texture at a **microscopic level**. When brushing, **black quartz releases negative ions**, which are **proven to prolong the clean feeling of your teeth**, effectively disrupting harmful bacteria.
The Development of the VBO Premium Toothbrush
The VBO Premium Toothbrush was developed by Dr. Vesna Kaloh in collaboration with **Kanagawa Dental University in Japan**. Dr. Kaloh is an **award-winning dentist** and one of the **world’s leading experts in Invisalign orthodontics**.
The toothbrush’s development is based on research conducted at **Kanagawa Dental University**, which demonstrated that **black quartz bristles remove up to 40% more plaque** than a **regular toothbrush**, even **without using toothpaste**. Pretty impressive, right?
Where to Get the VBO Premium Toothbrush?
