Kuretake No. 8 Fountain Brush Pen
In addition to the classic No. 13, Japanese Kuretake makes several brush pens in different designs, perfect for artists or calligraphy lovers. This model is long and narrow, which makes it easy to write and draw with. Use it at least once a month to keep it frm drying out, but if it does, please moisturize the brush by leaving it in water overnight. The brush comes with two black ink cartridges, and more can be found here.
