Tombow AirPress All-Weather Ballpoint Pen

The Tombow AirPress All-Weather Ballpoint Pen (BC-AP) is built for uncompromising performance in extreme job-site, field, and outdoor conditions. Equipped with Tombow’s patented piston-drive mechanism that actively compresses air to pressurize the ink cartridge with every click, this compact Japanese tool writes reliably upside-down, on wet paper, and in dusty environments.

Key Features

• Patented Piston AirPress Drive: Every click of the push button activates an internal piston, instantly compressing air to force ink smoothly to the pen tip without gravity dependency.
• Uninterrupted All-Weather Writing: Writes effortlessly overhead/upside-down, across rain-damped or wet paper, and in dusty construction environments.
• Cushioned Elastomer Grip: Full-length soft rubberized sleeve provides maximum tactile traction, even with wet hands or heavy work gloves.
• Heavy-Duty Flexible Wire Clip: Wide-opening spring wire clip clamps securely onto thick clipboards, tool belts, and pockets, featuring an integrated lanyard loop.
• Six High-Visibility Colorways: Offered in Clear Transparent, High-Vis Orange, Vivid Red, Electric Blue, Bright Yellow, and Stealth Black.
