Thanks for the video, I found it very interesting. One brush type that is commonly found in Japan; especially in the region of Nara, is the Pig hair brush. They are used for brushing/cleaning work in Art and in some instances as flat heads used typically for applying wash's.
Un país moderno que cuida sus tradiciones. El cuidado que ponen en todos los detalles para "fabricar" un pincel, algo a lo que se da tan poca importancia en occidente, son admirables.
Could you please explain me clear that what cremation of the owner brushes that those brushes must go with its owner, or is it just a cremation of the brushes festival?
