Tachikawa Pen Nib Holder features special double rubber rings at the tip; the smaller ring is compatible with smaller round nibs and the larger ring is compatible with regular nibs. The rubber ring holds the nibs tightly when drawing.
The pen holder is 14 cm long and has a sky blue rubber grip.
Please note this is a pen body only and no nibs are included
There is also a nifty plastic cap to protect your nib, when not in use.
