Description The Kaweco Classic Sport fountain pen in Iridescent Pearl will be available for only about 6 months, so grab this beauty while you can! The Classic Sport is a smaller pocket-sized pen that features a smooth-writing steel nib and luminous mother-of-pearl inspired plastic barrel and cap. The Kaweco Classic 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!
