The brushes are sustainably harvested from managed forests and finished naturally with purified linseed oil and beeswax. No toxic lacquers or finishes of any sort are used. The bristles are made of wood or natural boar bristles. Wood bristles are made from the smooth white wood of the hornbeam tree (from sustainable, managed forests, of course), chosen for its break-resistant grain. Ethically obtained wild boar bristles are hand-set into the boar bristle brushes. The supreme quality of these handmade brushes is evident in the clever design and are designed to last a lifetime.
