The Hardcore Hardware Australia TWI-01C features a dome shaped crown with integrated tungsten carbide glass breaker. At the opposing end we have incorporated a pointed tip for sensitive investigative work. The entire shaft of the pen is constructed from 6000 series, non-reflective; black anodized aluminium for extreme longevity and wearability.

The TWI-01C includes a series of O-rings making it completely waterproof when the cap is screwed down over the writing tip. Knurling along the pen aids a positive grip.

When it comes time to replacing the refill the TWI-01C will accept standard Parker and Fisher Space Pen refills, we have found these refills to offer superior performance.
