Black Liquid Ink In The Eye UB-150 Rollerball

This is the black version of the uni-ball Eye UB-150, a liquid ink rollerball pen with a 0.5mm line and a see-through ink chamber that shows how much ink is left.

uni-ball's page says the Eye has an ink flow system that ensures continuous flow and high writing performance until the very last drop. uni-ball's 2026 catalogue labels the UB-150 as Micro 0.5mm, and its page says the Eye Micro suits fine writing, sketching and technical drawing. The page also shows the uni Super Ink logo, and Mitsubishi Pencil Australia advises that pens carrying it are water, fade and time resistant.

A 0.5mm line is a finer one, which suits notes, forms and detailed writing in black. Because the ink chamber is see-through, a user can check the ink level at a glance on a shared desk. It is sold by the box of 12, so a department is stocked in one order.

The other colours in this model are at rollerball pens. The wider uni-ball range is at uni-ball, other pen types at pens, and the rest of the desk at writing supplies.
