Description The Kaweco AL Sport Black ballpoint is made of solid black aluminum and has a sporty and compact look with a metal Kaweco logo on top of the knock button. The refill extends and retracts by pressure the knock button on the top of the pen. The Kaweco add-on clip in either silver or gold metal, or the Deluxe clip in Raw Bronze, Gold or Chrome, is a nice extra, especially if you keep the pen in a shirt pocket! Replacing the refill for this pen seems daunting, since the pen is almost entirely one piece, so here is the scoop - you have to unscrew the top button and the refill will come out as well. Make sure to push the replacement refill firmly in the holder before inserting it back into the barrel. The Kaweco AL Sport ballpoint measures approximately 4.1 inches, and uses the Mini ballpoint refill.
