The Nano-b antibacterial toothbrush features self-cleaning bristles infused with gold and bamboo charcoal. The bristles are arranged in a double row, allowing deeper penetration into the spaces between the teeth when pressure is applied. The tips of the bristles are rounded, preventing scratches and micro-cuts on the gums and tooth enamel. Nano-b toothbrushes are packaged in a reusable container. When opening, remove the label from the lid to allow ventilation of the container.
