I bought this at Nakagawa Masashichi Shoten and used it a few times. Sunair Super Tonton ■Materials/Ingredients: Handle: Natural wood (Nordic beech) Pin: Moso bamboo (Taiwanese) Rubber base: Synthetic rubber (NBR) Shaft: 66 nylon ■Size: H30 x W8 x D5cm ■Weight: 102g Product Description This is a health brush designed to be simple and easy to use, with a focus on natural materials, based on the motto "gentle to people, the scalp, and hair." If you massage rhythmically with "Tonton, ton," both your mind and body will relax. The head part uses bamboo pins, which are effective in promoting blood circulation in the body. You can use the flexible neck part to massage your shoulders and lower back, or gently press the bamboo pin part to improve eye fatigue and swelling, and you can use it on your whole body. Thank you.
