Equipped with APS! Compressed air transforms your writing.

The APS (AirPress System) is a unique mechanism that creates compressed air with each knock and pushes out ink.

It ensures reliable writing even in demanding situations, such as speed writing, writing with your eye up, and writing on damp paper.

This knock-type pressurized oil-based ballpoint pen is packed with features for active use.

Knock Pressure Mechanism: With each knock, the piston compresses the pressure chamber, sending compressed air to the refill (core), and pushing out the ink.

You can write clearly without smudging, even when writing quickly, with your eye up, or on damp paper.

Rubber Body: The body surface is finished with a soft resin (elastomer), ensuring a secure grip even with wet hands or while wearing gloves.

*The transparent barrel is made of acrylic resin.

Strong Clip: The strong wire clip combines flexibility and strength to open wide. It securely holds everything from a single sheet of copy paper to thicker materials.

Short Body: At 122mm long, it's ideal for portability. It's about 20% shorter than a standard office ballpoint pen (around 150mm), allowing for quick tapping and making it ideal for writing and shorthand in tight or crowded spaces.
