Yasutomo Best Niji Round Waterbrushes

The “Original” Waterbrush® 

Waterbrushes started appearing in Japan in the 1990s when artists emptied the ink of regular brush pens and filled them with water. Brush pen makers soon began to reproduce these designs with translucent barrels and no ink, calling them mizu-fude, which translates to “water-brushes”. Soon after they gained popularity in Japan, Yasutomo introduced the waterbrush to the U.S. market.
