Key specs: Visible line width of 1.0 mm, smooth oil-based ink for consistent flow, fast-drying to reduce smears on forms, a soft, comfortable grip for long writing sessions, and a retractable tip for convenient one-click use.

Oil-based ink typically offers a smoother glide and stronger on-paper performance, with faster drying on many surfaces. It tends to be more resistant to smears on receipts and forms compared to some gel inks, while still delivering clear, bold lines at 1.0 mm.

Yes. A 1.0 mm line is highly legible and stands out for emphasis on lists, forms, and registrations—making it easy to read at a glance.

To extend the tip, press the top button once. To retract, press again or click the mechanism back into place. The tip stays protected when not in use, helping prevent ink marks when stored in pockets or folders.

It features a soft, comfortable grip designed for extended writing sessions, helping reduce fatigue during long note-taking or form-filling tasks.

Laknock pens typically use replaceable refills within the Laknock line. Check compatibility with Uni-ball Laknock oil-based refills to continue using the 1.0 mm mechanism without needing a new pen.

Yes. The ink is designed for everyday documents and forms, with quick-drying properties that help minimize smudges. As with any writing instrument, avoid ingestion and keep out of reach of small children.

If you want a similar 1.0 mm line in a different color, you can opt for the blue variant with the same ink and tip size. For a finer line, you might choose a 0.7 mm option. Quick comparisons: 1.0 mm red (current product) vs 1.0 mm blue: same performance, color difference; 0.7 mm black: finer line with a different feel.

Great for checklists, inventories, registrations, receipts, and daily mark-ups where a bold, legible line is helpful. It’s also suitable for classroom notes and where quick, readable markings are desired.

Store with the tip retracted when not in use to protect the nib. Keep away from extreme heat and direct sunlight. If ink leaks or smears occur, wipe the tip lightly and avoid pressing too hard on glossy surfaces to prevent feathering.
