This portable water brush comes from a historical art supply shop in Ginza, Tokyo. The shop was founded in 1917, by Hyozo Furuhashimoto, and is run today by a married couple who greatly admire his work. They manufacture all of their supplies, with 26 being patented designs. Item details: The brush has a soft plastic barrel to store water, which seeps into the bristles when squeezed. This eliminates the need for a separate water container when traveling, as the perfect companion to an artist on the move.
