Uni Multi-Pen Jetstream EDGE3 white (0.28 mm)

The Uni Jetstream EDGE3 in White is a three-colour ballpoint with oil-based 0.28 mm refill – one of the finest line widths available in a multi-pen ballpoint. The sleek metal barrel with white finish lies cool and precise in the hand. Three colours – black, blue, red – are activated individually via a twist mechanism on the push button.

Features

• 0.28 mm oil-based refill: Jetstream ink with low viscosity flows smoothly, dries quickly and leaves sharp, rich lines – no smudging, no feathering. Perfect for narrow-ruled notebooks or densely-packed planners.
• Archive-quality ink: Water-resistant and lightfast – suitable for signatures, contracts and archival documents.
• Twist mechanism instead of push-button clicking: A smooth twist of the push button activates your chosen colour – no clicking, no slipping.
• Replaceable refills: The barrel section unscrews; the SXR-203-28 refill can be replaced individually without replacing the entire pen.
• Compact format: 142 mm length and 10.8 mm diameter – slim enough for tight pen holders in notebook covers or pocket diaries.
• White finish: Matte, even white on a plastic-metal construction – a calm, clean look without high-gloss effects.

Use & Tips

• The 0.28 mm line width is ideal for small handwriting in pocket diaries, narrow-ruled planners and dot-grid notebooks – even where 0.5 mm refills take up too much space.
• Thanks to the fast-drying oil-based ink, the EDGE3 is practical for left-handers too: the ink barely smudges as you write.
• Colour changes work cleanly: black for body text, red for priorities, blue for additions – without changing your grip.
• When replacing the refill, pull the barrel section straight and evenly – the connection is snug but releases by hand without tools.
• The fine tip is sensitive to heavy writing pressure; a light, relaxed approach produces the cleanest lines.

For Planner Enthusiasts

Anyone who plans in tight spaces – such as Hobonichi format or densely printed diaries – knows the problem with overly thick refills: lines overlap, writing becomes illegible, priority corrections in red no longer stand out. The SXR-203-28 refill addresses exactly that: thanks to the oil-based formula, the line remains defined and consistent even at 0.28 mm, without the capillary effects that water-based inks show on thinner paper. Combined with the three-colour mechanism, this creates a compact tool for structured colour-coding in pocket format.
