Replacement head for our bamboo dish brushes. Our brushes are made from sustainable bamboo and 100% plant fibre sisal bristles. The head twists off and you can add a replacement! As a natural fiber, sisal is a renewable and sustainable material. Sisal fibers come from Agave Sisalana cactus. At the end of its life cycle, sisal is 100 percent biodegradable.  Dimensions: 4.5cm diameter. Bristles are 2cm long. Please note: this is a replacement brush head only, it does not include the Brush handle. You can shop our Bamboo Dish Brush here.
