Every day we make tons of choices that will impact the environment. Sometimes it's a big decision, sometimes it's as small as changing your toothbrush! This is the first and only toothbrush to be made with 100% plant-based, petroleum free bristles. On top of that, it's vegan, water-neutral and fair. What's not to love? PRODUCT DETAILS This bamboo toothbrush has natural, extra soft, straight-trimmed bamboo based bristles for the efficient cleaning of extra sensitive teeth and gums. The bristles are made from bamboo dust mixed with nylon 4 - approximately 90% bamboo, 10% nylon. Nylon 4 is a BPA and phthalate free, naturally biodegradable polyamide and is widely considered as one of the most tolerable plastics from a health point of view. The bamboo mix bristles are made by steaming and drying bamboo material which is then ground to dust. This dust is mixed with Nylon 4 and pulled into the bristles. Packaged in a biodegradable recycled brown paper sleeve and a recycled Kraft card box. It measures approximately 17.5cm x 1.4cm x 1.7cm (at the widest point). CARE INSTRUCTIONS Always let the toothbrush dry thoroughly and replace it every 2- 3 months. When the toothbrush has come to the end of its life, it is recommended to remove the nylon bristles from the bamboo before disposal due to the different times they take to biodegrade.   REPLACEMENT FOR... Plastic toothbrushes! Over a billion toothbrushes in the US alone are used and disposed of each year, amounting to approximately 23,000 tonnes of landfill each year. horrific! The plastic they're made of will not break down in our lifetime... nor within the lifetime of our children or our children's children!
