Fountain pen quality with the convenience of a rollerball

The Uni-Ball Eye UB-150 combines a unique ink flow system with Super Ink pigment to deliver rich, consistent liquid ink writing with a see-through barrel that lets you monitor ink levels at a glance.

The Eye's gravity-fed ink delivery draws ink smoothly to the stainless steel tip without relying on pressure, producing a flowing, fountain-pen-quality line that stays consistent from the first stroke to the last drop. Black at 0.5mm is a popular choice for fine note-taking, technical annotations, and professional correspondence where a vivid, precise line matters. The see-through ink chamber is a practical feature for anyone who relies on a pen heavily and needs to know when a replacement is due.

Super Ink is waterproof once dry, fade resistant, and tamper proof, making the Eye a reliable choice for important documents and records. Supplied in a box of 12 for offices, studios, and shared workspaces.
