Description The Kaweco Brass Sport fountain pen is a smaller pocket-sized pen that features a smooth steel nib and barrel and cap made of raw brass that and will develop a unique patina and pattern of scuffs and scratches over time as you use the pen. The Kaweco Brass Sport fountain pen is quite short when capped, but when posted, it is a comfortable 5.25 inches long in the hand. The cap screws on to close, and accepts both standard international cartridges, which are included, or a short converter which is available separately. The add-on clip in either silver or gold metal, or the new Deluxe clip in Raw Bronze, Gold or Chrome, is a nice extra, especially if you keep the pen in a shirt pocket!
