This wooden penholder from Tachikawa can accommodate all sizes of Nikko and Tachikawa Nibs. This cherry wood holder has a rubbery grip for comfort. The head of the holder has several rings to accommodate different nib sizes. Highly Recommended by Kaylyn at Push/Pull. "I almost always use a Tachikawa nibholder if I'm drawing with nibs. They're super versatile, and can even be used with scratchboard nibs."
