Penholder for crow quill drawing nibs

Penholder for crow quill drawing, calligraphy and cartography nibs. This penholder is very thin and is used to mount the three very fine cartography nibs (crow quill) in our range: Crow quill 659, Long shoulder 850 and Mapping 2788. Be careful, the attachment is delicate, the nibs can be inserted by holding them with your left hand and gently inserting them into the center pin, at which point, you rotate the penholder to screw it onto the nib and insert the nib deeper (see photo).
