The ZEN Rollerball combines simple elegance and practical functionality. In the cap is a ring magnet, a light "snap" and the cap sits in its place. No more thread. Who likes the cap can write on the end piece.
The rollerball comes with a ceramic-tipped refill made by Schmidt here in Germany for a very smooth writing experience. The refill is, of course, replaceable.
