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.

Yes, they are designed to fit any standard mechanical pencil that accepts 0.9mm lead.
2B indicates a softer, darker grade of graphite, which is ideal for bold writing and sketching.
Due to the dark 2B grade, they are more susceptible to smudging than harder leads like HB or H; handle your work with care.
Each tube contains 36 individual 60mm lead sticks.
No, the molecular ceramic structure is a proprietary binder technology designed for strength and is safe for general writing use.
Ensure you are not extending the lead too far out of the sleeve, which increases leverage and breakage risk.
Check for a lead jam inside the nose cone; use a thin pin or wire to clear any small broken segments from the tip.
To insert these leads into your mechanical pencil, ensure you are using a device rated for 0.9mm leads.
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.
