Diamond Knurl Pen Kit Starter Set — 4 Ballpoint Pen Kits

Build a striking collection in one order with the Diamond Knurl Pen Kit Starter Set. This set bundles one kit in each of four two-tone finishes — Chrome & Gun Metal, Chrome & Satin Chrome, Ti Gold & Gun Metal, and Black Chrome — every kit featuring the same precision-machined diamond knurl texture and three-piece decorative center band that give this Sierra-style kit its signature look.

What sets this starter set apart is that it takes the guesswork out of tooling — a bushing set for the build and all four refills are included, so you're ready to turn as soon as your blanks arrive. It's the simplest way to stock four of the Diamond Knurl's best two-tone finishes at once without placing four separate orders.

Features

• Diamond knurl texture on the hardware components adds a premium machined aesthetic and a confident grip

• Three-piece decorative center band creates a bold visual break between upper and lower barrels

• Sierra Twist Style mechanism — proven, smooth, and reliable, extends and retracts the tip cleanly with a single twist

• Uses standard Sierra 20A tooling — no new setup required for experienced Sierra turners

• Threaded nib end allows easy refill replacement without touching the upper components

• Parker-style refill included — ready to write the moment assembly is complete
