Everyday writing instrument

The uni-ball 1921065 is a capped rollerball stick pen with a 0.5 mm conical tip that produces extra-fine black lines. Water-based chemical-dye ink bonds to paper for resistance against water, fading and fraud. The smooth barrel has no visible ink window and is made from recycled material. Suitable for notes, signatures, diagrams and detailed creative work.

Ready to use immediately

Remove the cap and write; no refilling or setup is required. The micro tip can feel scratchy on very rough paper and the water-based ink may take a moment to dry on glossy surfaces, so left-handed writers should allow a brief pause to avoid smudging. Capped design prevents the tip from drying out between sessions.

Consistent line quality over long sessions

Ink flow remains steady during extended writing because the conical tip and Super Ink formulation resist skipping and feathering. The smooth grip requires no extra pressure, reducing hand fatigue when filling pages of notes or detailed drawings. Performance stays uniform from the first stroke until the cartridge is depleted.
