0.28 Ultrafine Jetstream 0.28mm

Ultra-fine, challenging the limits of oil-based ballpoint pens
World's smallest ball diameter of 0.28mm, the first oil-based ballpoint pen
* As of August 2019 (based on our research)

Ultra* low-friction [Jetstream ink] enables unprecedented fine writing with an ultra-fine ball diameter of 0.28mm.
The world's smallest, ultra-fine ball with a diameter of 0.28mm*, a world first in the oil-based ballpoint pen category. Compared to our gel ink ballpoint pens with the same ball diameter, the drawing line width is finer.
The use of low-viscosity oil-based ink [Jetstream ink] allows for quick-drying and smooth writing of thick, clear strokes.
* As of August 2019 (based on our research) * The replacement lead is available in black, red, and blue

Newly developed [point tip] for easy viewing of the writing surface
The newly developed [point tip] is slim and narrow toward the nib, allowing the nib to be seen clearly even when performing fine writing tasks.

Main body shaft that combines functionality and design
The nib is made of metal, and the grip is designed with a thin line to prevent slipping. The center of gravity has been shifted to the nib side to ensure stability when writing fine strokes.
*Design
The thin wire clip and the radial straight lines created by the hexagonal shaft express the thin, sharp lines that can be drawn with the Jetstream Edge. The design visually shows the center of gravity, which is shifted to the nib side by the shape that tapers toward the back end.
