APS (AirPress System) is a new mechanism that creates compressed air each time it is knocked and pushes out ink.

We promise reliable writing even in hard scenes such as "quick writing", "upward writing", and "writing on damp paper".

A knock-type pressurized oil-based ballpoint pen with a full range of functions for active use.

Knock pressurization mechanism
Each time the piston is knocked, the piston crushes the pressurizing chamber and sends compressed air to the refill (core), pushing out the ink.
Ink can be written clearly without fading even in quick writing, upward writing, and writing on damp paper.

Rubber body
The surface of the body is finished with soft resin (elastomer), and it holds firmly even with wet hands or gloves.
* The transparent shaft is made of acrylic resin.

Strong clip
It opens wide with a strong wire clip that combines suppleness and toughness. Holds firmly from one sheet of copy paper to thick ones.

Short body
A total length of 122 mm suitable for carrying.
Since it is about 20% shorter than an office ballpoint pen (standard around 150 mm), it can be knocked quickly and is suitable for writing and shorthand in narrow or crowded places.

Refillable
Refillable with Tombow BR-SF Refill core.
