The Tail Tamer Wood Series Small Horsehair Brush from the Great Grooves Wood Series has been produced from the wood of Paulownia trees. The Paulownia is a fast-growing tree and also known as the Princess Tree which is used all over the world for reforestation and to help stop erosion and also thrives in areas where many trees won't grow. The wood from these trees is very light, as well as being resistant to warp and rot. This brush is a wood version of our favorite horsehair brush.
