The FUDENOSUKE has an elastic tip, which is narrower and sturdier than those on the ABT Dual Brush Pens. The calligraphy pen allows a swift, controlled movement of the pen and is particularly well suited for small letters and embellishments. The line width varies from very fine to thick according to pressure applied to the tip. The ink is water-based with colour pigments and is odour-free. Ink colour Black.
