Rotring "Rollkuli" pen - World's first refillable rollerball - 1955
I am selling this very special Rotring "Rollkuli" pen, made to compete the ballpoint in the fifties: instead of the typical Rotring Stilo this pen features a tiny ruby rollerball tip. The pen does use regular fountain pen ink and has a classic piston mechanism. The cap of the pen has typical hard rubber discoloration and is a bit brown. The pen has been used but still looks quite good, it has a curved tip which takes some getting used to, but then it writes smoothly (see pictures).
