Sustainable oral hygiene for children - The wooden toothbrush from WALDKRAFT from the Black Forest is designed to feel gentle in the mouths of your little ones. In doing so, we completely avoid harmful plastic. The toothbrushes as well as the packaging are biodegradable and compostable. Made in Germany - The toothbrushes are manufactured with great love and precision craftsmanship in the Black Forest and do not have to be transported long distances as with standard bamboo toothbrushes. Better alternative to bamboo - We only use high-quality beech wood - FSC 100% certified, which means that you buy a piece of wood from responsibly managed forests. BIO-NYLON BRISTLES - The trimming of this brush is based on castor oil. The oil, which is extracted from the plant, is processed into organic nylon and is therefore BPA and petroleum free.
