Full details
The Pentel Ain Lead Refill 0.9mm in 2B grade is designed for students, artists, and professionals who demand a balance between bold, dark lines and structural integrity. Featuring an advanced molecular ceramic frame, these leads provide an exceptionally smooth writing experience while maintaining superior break-resistance compared to standard graphite refills. While they offer excellent performance for heavy-handed writers, users should note that the softer 2B formula may smudge more easily than harder grades if not handled with care.

FAQs
Are these leads compatible with all 0.9mm mechanical pencils?
Yes, they are designed to fit any standard mechanical pencil that accepts 0.9mm lead.
What does 2B mean?
2B indicates a softer, darker grade of graphite, which is ideal for bold writing and sketching.
Are these leads smudge-proof?
Due to the dark 2B grade, they are more susceptible to smudging than harder leads like HB or H; handle your work with care.
How many leads come in a tube?
Each tube contains 36 individual 60mm lead sticks.
Is the ceramic frame harmful?
No, the molecular ceramic structure is a proprietary binder technology designed for strength and is safe for general writing use.
Troubleshooting
Lead keeps snapping during writing
Ensure you are not extending the lead too far out of the sleeve, which increases leverage and breakage risk.
Lead does not advance when clicking
Check for a lead jam inside the nose cone; use a thin pin or wire to clear any small broken segments from the tip.

Setup, Compatibility & Care
To insert these leads into your mechanical pencil, ensure you are using a device rated for 0.9mm leads.
- Remove the pencil cap or eraser unit to expose the lead reservoir.
- Gently drop the lead stick into the reservoir, taking care not to overfill, as this can cause jamming.
- Replace the cap and click the mechanism several times until the new lead advances.
For care, store the lead tubes in a cool, dry place to prevent moisture from affecting the graphite binder. When cleaning your pencil, ensure no lead fragments remain in the clutch area, as this can prevent the new lead from gripping correctly.
