Frequently Asked Questions

Will the brass change color or develop a patina?

Yes, because the brass is raw and uncoated, exposure to air and natural skin oils will cause it to darken and form a distinctive, protective vintage patina unique to each user.

How can I restore the pen's original bright shine?

If you prefer a bright golden luster rather than a weathered patina, you can gently polish the bare metal with a specialized brass cleaner or polishing cloth.

Does the pen take standard ink cartridges?

Yes, the Brass Sport accepts standard international short ink cartridges; one royal blue cartridge is included inside the barrel.

Can I use bottled ink with the Kaweco Brass Sport?

Yes, the pen can be filled from bottled ink using an optional Kaweco mini piston or squeeze converter (sold separately).

Is an octagonal pocket clip included?

The pen features a sleek clip-less octagonal cap to prevent rolling; optional Kaweco bronze, raw brass, or silver slide-on clips are available separately.
