Uni-Ball Gel Pen One avocado green

The uni-ball Gelroller One in Avocado-Green is a Japanese gel pen with waterproof pigment ink – engineered for even, clean writing in a fresh, vibrant colour. The ink adheres to paper fibres rather than soaking in, preventing bleed-through on smooth paper and keeping the colour precise on the line. The slender white barrel with metal clip and colour-coded ink window at the top makes this pen a reliable everyday companion.

Features

• Waterproof pigment ink: The ink is not archival, but water-resistant – it doesn't smudge after drying and retains its colour strength even in damp conditions.
• Avocado-Green pigment ink: The pigment formula delivers this mid-tone green vibrantly to the page – more luminous than comparable dye-based gel pen inks.
• Fibre-adhering ink formula: The specially developed gel ink sits on paper fibres rather than soaking in – the result is sharp writing without fuzzy or feathered lines.
• 0.5 mm line width: Fine, controlled line – suitable for small handwriting, margin notes and neat layouts in notebooks and planners.
• Colour indicator on barrel: The colour element at the top of the pen shows the ink colour at a glance – handy when you have several pens in a collection.
• Metal clip: Sleek, sturdy metal clip – holds securely on notebook covers, shirt pockets and ring binders.
• Compact, slender design: 140 mm length and max. 10.5 mm diameter – light in hand and comfortable to hold even during extended writing sessions.

Use & Tips

• Bullet journalling and planners: Avocado-Green works well as an accent colour for categories, habit trackers or weekly overviews – the 0.5 mm tip is fine enough for small grid cells.
• Annotation and highlighting: Pigment-based coloured gel pens are ideal for colour-coding in notebooks without other inks running – especially on smooth, calendered paper.
• Paper recommendation: The ink flows most evenly and dries quickly enough for right- and left-handers on smooth, ink-friendly paper. On highly absorbent paper, the colour may appear duller.
• Multi-colour use: The colour indicator at the top of the pen makes it easy to sort and quickly pick out from a pen cup – ideal when using several uni-ball One colours together.
• Not archival: The ink is water-resistant but not archival – choose different ink for documents that require long-term preservation.
