uni-ball ONE 3 Three-Colour Gel Pen — 0.38mm or 0.5mm
The uni-ball ONE is Mitsubishi Pencil's answer to a simple complaint: gel ink that looks faded on the page. Its pigment-rich ink sits on top of the paper fibres instead of soaking in, so even fine lines read dark and saturated.
The uni-ball ONE 3 puts that ink into one pen with three colours — black, red, and blue. Instead of separate clickers, you twist the barrel to bring each colour forward, which keeps the body slim and uncluttered. A stabiliser inside balances the centre of gravity so the tip doesn't wobble as you write. Light at about 15g and 129mm long, it's an easy single pen to carry for notes, marking up, and colour-coding.
