Tombow MONO Graph Multi vs ZOOM L105 Review: Japan's Most Sophisticated Ballpoint Pens for UK Writers

Tombow is a Japanese writing instrument brand with over a century of history, celebrated for producing pens that combine exceptional engineering with refined aesthetics. Two of their most distinctive ballpoint offerings represent different philosophies of what a ballpoint pen can be: the Tombow MONO Graph Multi — 2 Color 0.5mm Ballpoint Pen + 0.5mm Pencil, a multi-function instrument that combines two ink colours and a mechanical pencil in one body, and the Tombow ZOOM L105 Oil-Based Ballpoint Pen — 0.5mm, a premium single-function pen with a distinctive architectural design and oil-based ink that writes with exceptional smoothness.

Tombow MONO Graph Multi: Three Functions, One Elegant Pen

The MONO Graph Multi is a multi-function pen that combines two ballpoint ink colours (typically black and red) with a 0.5mm mechanical pencil in a single, slim body. For UK students, professionals, and anyone who annotates, marks up, and corrects documents, this combination is genuinely useful — black for writing, red for corrections and emphasis, pencil for erasable notes and sketches, all in one instrument.

Why Multi-Function Pens Matter

The practical case for a multi-function pen is simple: fewer instruments to carry, fewer instruments to lose, and the right tool always to hand. For students who annotate textbooks and lecture notes, the ability to switch between black writing, red correction, and pencil sketching without changing instruments is a genuine productivity advantage. For professionals who mark up documents, the same logic applies.

MONO Graph Quality

The MONO Graph name is Tombow's premium designation — the same brand as their celebrated MONO erasers and MONO drawing pencils. The ink quality is consistent with Tombow's reputation: smooth, consistent flow with minimal skipping, and a line that's dark and legible from the first stroke.

Tombow ZOOM L105: The Architect's Ballpoint

The ZOOM L105 is a different kind of pen entirely — a single-function, premium ballpoint with a distinctive architectural design that makes it one of the most visually striking pens in Tombow's range. The L105 designation refers to its length (105mm), and the ZOOM series is characterised by its bold, geometric design language that sets it apart from conventional pen aesthetics.

Oil-Based Ink: The Smoothest Ballpoint Experience

Oil-based ballpoint ink is the traditional ballpoint formula — thicker than water-based gel ink, it produces a slightly different writing experience that many writers prefer for its consistency and reliability. Oil-based ink is less prone to smearing immediately after writing, making it particularly suitable for left-handed writers and anyone who writes quickly. The 0.5mm tip produces a fine, precise line that's ideal for detailed writing and annotation.

The ZOOM Aesthetic

The ZOOM L105's design is bold and architectural — a pen that makes a statement on the desk and in the hand. For UK professionals who want a pen that reflects their design sensibility, the L105 is a compelling choice: functional, beautiful, and distinctively Japanese in its design philosophy.
