Kaweco Classic Sport Liquid Ink Roller Ball Pen - Medium Point - Black Body

I found this brand from another retailer but didn't want to wait for international shipping. This is a different rollerball than the norm. It takes the international short ink cartridges often associated with fountain pens. The pen rolls smoothly and writes well. It is also very compact and it and its companion fountain pen are in the case and go with me most places. Excellent pen and most excellent value.

These also make a super ballpoint if you want - take out the rollerball refill, add a parker size ballpoint refill WITH A SPRING, and you are ready to go.
