What does it replace? Our bamboo toothbrush replaces the old nasty plastic toothbrush that we have all been accustomed to. A plastic toothbrush takes about 400 years to decompose, whereas bamboo only takes around 4-6 months if you are using a home composter and about 3 years if you put it back to the soil to decompose on its own. You can imagine the difference, right? Why is it better? Bamboo is the fastest growing plant on earth and can be harvested in a span of about 5 years. This means that we do not have to worry about exhausting this resource unlike other plants that takes more than a decade to mature before they can be harvested. To top it all off, bamboo is 100% natural and safe for our environment. Is it worth it?
