Pt nano Platinum Nano Toothbrush manmou for children, blue, 1 piece

■Platinum nanoparticles are applied to the tips of the toothbrush head bristles. Platinum nanoparticles, which have mainly been used on fibers up until now, are now applied using our unique technology. Ascorbic acid and citric acid are blended as protective agents.
■The ultra-fine bristles are as soft as a brush, allowing you to brush your gums. (Approx. 20,000 bristles for adults, approx. 10,000 bristles for children)
■The bristles are 0.08mm fine. You can brush the gaps between your teeth.
■You can brush your teeth with just water, without brushing your teeth. *Platinum nanoparticles are certified as a food additive by the Ministry of Health, Labor and Welfare, so they are safe to put in your mouth.
■A typical toothbrush has an average of about 1,000 bristles, and the bristles are 0.2mm fine.
◆Materials for children: PP (handle), PBT (bristle material), soft (bristle hardness), 60℃ (heat resistance)
