The Tactile Turn Ultem Bolt Action Pen is a limited-production writing instrument crafted from Ultem® (polyetherimide, PEI), a high-performance engineering thermoplastic prized for its exceptional mechanical strength, heat resistance, and natural amber translucency. This edition takes the brand’s iconic bolt-action design and reinterprets it in an advanced polymer that is both lightweight and visually distinctive, offering a unique contrast to the all-metal construction of the standard lineup.
Materials & Construction
Material: Ultem® (PEI) – a semi-transparent, amber-toned thermoplastic used in aerospace and medical industries.
Strength & Durability: High tensile strength, dimensional stability, and excellent resistance to solvents and chemicals.
Machining: Precision CNC-machined with Tactile Turn’s signature **grooved barrel texture, ensuring both visual depth and enhanced grip.
Clip: Custom-machined titanium clip, bead-blasted for durability and secured with Torx screws.
Finish: Natural, uncoated finish—allowing the warm amber translucency of Ultem to remain visible and develop subtle depth over time.
Mechanism
Bolt Action: Precision-machined bolt-action mechanism, smooth and reliable in polymer housing, paired with a titanium bolt for longevity.
Operation: One-handed actuation with positive lock; engineered for repeatability and fidget-friendly operation.
Writing
Refill System: Parker-style G2 compatibility
Tip Alignment: Precision-machined nose cone ensures stable writing with zero tip wiggle, even with the lighter Ultem body.
Balance: Featherweight construction minimizes fatigue, while the grooved grip section maintains control during extended use.
