Kepler Pen

Gift box containing an AEON aluminum pencil, 1 Eternal lead, 2 graphite leads, and a leather pouch. Both types of leads are included; if purchased separately, the Eternal lead costs extra. Available in eight colors, comes in a reusable box with a card.

Aluminum pencil with a magnetically interchangeable tip. The Eternal tip writes for years without needing to be sharpened, and the graphite tip provides that classic HB feel. 134.6 mm long, weighs 27 g, with flattened sides to prevent it from rolling away.

The short AEON: 94.9 mm instead of 134.6 mm, so it fits in a jacket pocket or notebook loop. 23 g, aluminum, magnetic tip swap between Eternal and Graphite. Seven colors, flattened sides.

Ballpoint pen with a magnetic cap instead of a click mechanism: it aligns itself when closed and fits snugly without any play. 137 mm, 60 g, aluminum in eight retro colors. Refillable with standard G2 refills.

The Japanese Pilot LP3RF Juice Up gel refill for the ARC gel pen. Permanent and smudge-proof, available in black, blue, or red, and in line widths of 0.3, 0.4, and 0.5 mm. Also fits other pens in the G2 system.

Rollerball pen with Schmidt P8127 refill: writes more smoothly than a ballpoint pen, without the maintenance required by a fountain pen. 137 mm, 35 g, aluminum in eight colors. Magnetic cap that aligns itself when closed.

The minimalist version of the AEON: same magnetic mechanism, same 134.6 mm length, but without the wood veneer. All aluminum, throughout. Weighs just 27 g, available with an Eternal or graphite tip, and flattened sides to prevent it from rolling away.

Stainless steel clip for the ARC gel pen and the AEON pencil. 3.5 g; attaches without tools. This keeps the pen in your shirt pocket or notebook instead of rolling around in your bag.

The PEN in titanium: 75 g instead of 60 g for the aluminum version; feels noticeably more substantial in the hand. Magnetic cap that aligns itself when closed. 137 mm. Three finishes: matte titanium, DLC, and polished.

The INK in titanium: 82 g, corrosion-resistant, available in matte titanium or DLC. The nib by Peter Bock is available in stainless steel, black steel, titanium, or 14-karat gold, each in four widths. 152 mm long; converter included.

At 20 g, this is the lightest AEON. Magnesium weighs about a quarter less than aluminum while maintaining its shape. For long sketching sessions where every gram makes a difference in your wrist. 134.6 mm, magnetic tip replacement.

Solid brass, 52 g; develops a patina over time. The heaviest FLOW model and the only one that visibly changes over time. Schmidt P8127 refill for consistent ink flow. 137 mm long, magnetic cap without a click.

The ARC in titanium: 65 g instead of 35 g for the aluminum version, which ensures a smoother line when writing. Japanese Pilot Juice Up gel refill in 0.3 to 0.5 mm. Anti-roll design, self-aligning magnetic cap, 142.5 mm long.

The AEON in titanium. At 47 g, it’s noticeably heavier than the aluminum version, without being heavy. Titanium is corrosion-resistant and more scratch-resistant. Three finishes: matte, DLC-coated, and polished. 134.6 mm.

A fountain pen you can customize yourself: three colors, four nib materials ranging from stainless steel to 14-karat gold, and four nib widths. 152 mm, 70 g aluminum. A converter is included; standard cartridges also fit.
