ABOUT 7 BILLION OF PLASTIC TOOTHBRUSHES IS STORED AND DISPOSED OF 23,000 TONS PER YEAR. Our toothbrushes are packed in transparent biodegradable bags which are made of plant fiber (rest of corn starch). The bristles are made of bamboo fiber and Nylon4, which is biodegradable. Natural feeling in the hand and the mouth makes brushing becomes more pleasant. Toothbrushes are made of moso bamboo which is not eaten by Pandas. Bamboo is harvested and bought from private farmers. It is biodegradable.
