Crow quill pens have a cylindrical body that only fit a crow quill nib, which generally draws finer lines than a standard nib. A terrific starter for pen-and-ink sketching. For #102 nibs - Durable plastic holder is 5'' long and fits crow quill nibs #102, #107, and #108
We no longer carry the nibs, but they are widely available elsewhere ;-)
