RADIN G2 – Brass Ballpoint Pen, Parker G2 Refill

RADIN G2 is a handcrafted brass ballpoint pen featuring a twist-action mechanism, redesigned for Parker-style G2 refills.

While preserving the original RADIN's dimensions, distinctive knurled grip, and overall design, its internal mechanism has been completely re-engineered to accommodate the Parker-style G2 refill format.

Redesigned Mechanism

The RADIN G2 features a newly developed internal assembly, including a custom-designed adapter and reconfigured mechanical components.

This allows the pen to accommodate Parker-style G2 refills without changing its original dimensions.

The only noticeable exterior difference is the twist mechanism window, which has been repositioned approximately 10 mm higher on the body.

Material & Craftsmanship

Each brass component is individually machined on a manual lathe in the Thorn Mill workshop.

The precisely machined knurled grip provides a distinctive tactile experience, while the brushed brass finish highlights the material's natural character.

Optional Olive Wood Case

RADIN can be paired with an optional handcrafted olive wood case. Its solid brass cap features precision-machined knurling that echoes RADIN's distinctive grip, creating a visual connection between the pen and its case.

RADIN Hand-Turned Olive Wood Case is sold separately.
