Calamus Ballpoint and Rollerball: Two Playful Pens With Clever Design
A brass ballpoint with a gravity-operated tip and a click rollerball that trades a cap for a button. Here is what the pair does well and where to be careful.
Introduction
Some pens earn their place on a desk through heritage or nib refinement. The Calamus ballpoint and rollerball earn theirs through personality. Designed as companions to the Calamus fountain pen, this pair keeps the same compact, well-considered silhouette while adding two genuinely fun mechanisms: a gravity-operated tip on the ballpoint and a click action on the rollerball. Both arrive in simple cardboard tubes with minimal packaging waste, which is a nice touch at these prices. Here is how each one writes and holds up in daily use.
The Ballpoint: Brass, Small, and Surprisingly Comfortable
The ballpoint is a small pen, visibly shorter than a standard full-size writer, and it is a fun one. Its party trick is the gravity-operated tip: a quick flick of the wrist extends the point, which sounds like a gimmick until you realize how satisfying it becomes in practice.

Despite the compact size, it is comfortable to hold. The grip section carries fine grooves, the pen includes a roll stopper, and the barrel opens up to accept a Schmidt refill. The brass construction makes it feel genuinely solid in hand, with a reassuring heft that larger pens often struggle to match. The Schmidt refill writes in a smooth, consistent black line with no line variation, as expected from a ballpoint, and it works nicely for signatures and quick notes.
The Rollerball: A Click Mechanism Instead of a Cap
Most rollerballs are essentially capped pens with a rollerball tip. The Calamus rollerball takes a different, slightly cuter route: it is a button-operated click pen. That alone makes it stand out in a category where capped designs are the default.
In the hand it feels noticeably lighter than the brass ballpoint. The grip section is a touch girthier, the grooves match the ballpoint’s design language, and it carries a clip rather than a roll stopper. Writing is smooth and inky, exactly the experience that makes people prefer rollerballs over ballpoints in the first place. It writes quickly and cleanly, and like its sibling, it handles signatures well.
One caution: the clip is plastic and does not look particularly robust. If you tend to operate click mechanisms energetically, a little care goes a long way toward keeping that part intact. On a curved or uneven surface the clip does not fully stop the pen from rolling, though the ballpoint’s roll stopper performs reasonably well in practice.

Refills and Everyday Practicality
Both pens are refillable, which changes the ownership story considerably. The ballpoint takes a Schmidt refill and the rollerball’s cartridge pulls out with a bit of fiddling once you know the trick: push the mechanism down, open the front section, and draw the refill out. Because Schmidt refills are widely available, you never need to throw away an entire pen when it runs dry.

The rollerball’s small size also makes it genuinely pocketable and easy to drop into a bag, and the recyclable cardboard tubes keep the packaging footprint low.
Pricing and Value
The rollerball comes in at €19.95 and the ballpoint at €34.50. Buying from overseas means you skip the VAT, which makes them even more affordable. Considering the design work involved, the solid brass build of the ballpoint, and the reusable refills, both pens read as very good value rather than cheap novelties. The ballpoint’s higher price is easier to accept once you factor in the gravity mechanism and the brass construction.
Buying Advice
If you enjoy the ritual of a well-machined pen and want something with a bit of mechanical charm, the brass ballpoint is the one to pick. If you prefer a smooth, inky writing experience and a lighter, pocket-friendly shape, the rollerball is the better match, with the caveat of treating its plastic clip gently.

Choosing between them mostly comes down to writing preference: ballpoint convenience and heft, or rollerball smoothness and click-action fun. Either way, you get a refillable, thoughtfully designed pen that does not pretend to be more than it is, and that is exactly its appeal.
Conclusion
The Calamus ballpoint and rollerball are cute, affordable, and well-designed companions to the fountain pen in the lineup. The ballpoint brings a gravity-assisted mechanism and a solid brass body, while the rollerball offers a smooth inky ride in a lighter, click-operated package. The plastic clip is the only real point of caution, and even that is a minor one. For anyone who wants playful, refillable pens that stand out without a premium price tag, this pair is easy to recommend.
