The One Hybrid N rollerball pen features the Super-Flow-System for consistent, even ink flow and a hybrid needle tip for a pleasantly soft, yet precise, fine-line-writing experience. The large ink reservoir features an ink-level indicator, and the "cap-off ink" does not run dry even if the cap is removed for two to three days. The rollerball includes waterproof, documental ink, a high-quality metal clip and an ergonomic, rubberized grip. Produced CO2 neutrally.
