Designed with features to keep you writing in the worst of conditions, this everyday carry All-Weather Click Action Pen is anything but basic. A tough ABS plastic barrel survives being crushed, bent, or impacted. The triangular file textured grip helps you keep your hold with gloved hands or in wet conditions. Traditional clicker mechanism has an extra-large clicker button and heavy-duty spring for easy one-handed operation. The 0.8mm point pressurized cartridge with black ink writes through water, grease, and mud, in extreme temperatures (down to -30F), and even underwater.
