A Japanese inspired scrubbing brush, Eco Max have mixed two vegetable fibres together onto a rounded, comfortable to hold FSC certified rubber wood base to make the ultimate natural scrub brush. Tampico, a form of cactus is a strong yet softer fibre to give a good overall clean. It absorbs more water than any other natural fibre and releases it as you scrub. Rice root, which doesn't come from rice, is the root of a native grass called Zatacon from the Mexican highlands. The incorrect name probably derives from the Spanish word 'raiz', which means 'root'. It is naturally springy, slightly curly and extremely tough, which gives this spunky Scrub Brush that extra strength for hard scouring.
