Refills Guide
Everything about the refills
of the Eternal Pencil
How to change them, which to choose, how long they last — the complete guide to getting the most out of your pencil.
The Eternal Pencil owes its long lifespan to a screw-in refill system that is simple and clever. No special tools needed, no complicated steps.
How to refill your pencil
Turn the tip of the pencil counter-clockwise. The refill unscrews easily in 2 to 3 turns. No force needed.
Take out the worn refill. Its tiny size makes it negligible waste compared to an entire pencil.
Slide the new refill into the holder. It fits in the correct way automatically — it's impossible to insert it the wrong way.
Screw clockwise until the tip is firmly in place. Your pencil is ready — it writes immediately, with no break-in needed.
The sign that your refill is running out: the tip gradually becomes less precise and the line slightly broader. Replace it as soon as you notice a difference in quality.
Choosing the right refill
The universal reference. A precise, erasable line, ideal for everyday writing and note-taking.
Softer and darker. Perfect for artistic drawing and sketching.
For annotating and correcting. A vivid line, ideal for revision work.
Classic and easy to read. Ideal for diagrams or switching colors without switching pencils.
How long does a refill last?
- 📏 +1,300 km of continuous writing
- ⏱ +4,700 hours of effective writing
- 🔄 32× the lifespan of a regular pencil
For someone who writes one hour a day, a single refill lasts more than 12 years.
Tip: colored refills last slightly less long than graphite refills — expect 800 to 1,000 km depending on the color and writing pressure.
Frequently asked questions
Can the refill break inside the pencil?
No. The refill sits inside a protective mechanism that prevents breakage, even from impacts or drops.
Can different types of refills be combined?
Yes. All refills are compatible with the same pencil body. You can freely switch between graphite and color.
Does the refill wear faster with heavy pressure?
Slightly — heavy pressure accelerates wear by around 15 to 20%. But the lifespan still far exceeds that of any regular pencil.
