The HHA TWI-01 features a dome shaped crown constructed from high-grade stainless steel 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-01 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-01 will accept standard Parker and Fisher Space Pen refills - we have found these refills to offer superior performance.
