This brush is what it is. No more, no less. The name says it all: "purus." means not only pure, but also simple, honest, unvarnished and natural. Made entirely out of renewable raw materials, the brush is designed with sustainability in mind. So the handle convinces not only with its handy shape, but also because of the high-quality Swiss FSC beech wood. The handle is stamped with bristles made out of bio-based plastic. This means that the plastic does not consist of crude oil, but of renewable raw materials - in this case castor oil. Because even the most sustainable materials should not be wasted. In order to save natural resources, only the most essential materials are consciously used for this assortment. This brush is sustainable and effective - from head to handle.
