One pen body, four ways to write. The everline ONE takes any 2–2.3 mm refill, which means you can switch from sketching to signing in seconds. But which refill is right for what? Here is a practical guide.
Graphite (HB and 6B) – for thinking
Graphite is the most forgiving way to put ideas on paper. You can erase, shade and go back. HB is the all-rounder: crisp enough for notes, soft enough for sketching. 6B is much softer and darker – ideal for drawing, shading and expressive lines. One HB refill comes with every everline ONE. For a fine point, our sharpener brings the 2 mm lead back to a tip in a few turns.
Color – for drawing, highlighting and planning
Our color refills come in seven shades: black, red, yellow, ultra marine, green, teal and deep purple. Use them to color-code a planner, mark up a manuscript or draw. Because they are 2 mm leads, they behave like a colored pencil with the precision of a mechanical one.
Ballpoint (black and blue) – for signing
Some things need ink: contracts, forms, postcards. The ballpoint refill turns the everline ONE into a permanent pen for documents. Black for the formal stuff, blue if you want your signature to stand out from a printed page.
Eternal – for everything in between
The Eternal refill is a solid metal tip that writes without ink or graphite. It leaves a fine, silvery-grey line on paper and does not need sharpening or refilling in the usual sense – it is built to last as long as you keep it. Great for quick notes, sketches and anyone who is tired of empty cartridges.
Can I use refills from other brands?
Yes. Any refill between 2 and 2.3 mm fits – including standard D1 (ISO) refills and any 2 mm color or graphite lead. Slide it in from either end: press the body, insert, let go. No screwing, no aligning.
Which refill should I start with?
- Students and note-takers: graphite HB plus a color refill for highlighting.
- Designers and sketchers: HB and 6B graphite, plus Eternal for quick lines.
- Office and paperwork: ballpoint in black or blue.
- Can't decide? The Test all refills set lets you try every type.
