This rollerball from the cult manufacturer Ohto impresses not only with a strong appearance, but also with its technology. The ink gets on the paper through a special ceramic sphere. This ball is made of extremely hardened clay, whose finest unevenness ensures particularly good absorption of the water-soluble, light ink. A 0.5mm black refill is included. Other colors and line thicknesses are available as options. The rubberized grip provides extra comfort for longer writing.
