Mechanical Pencil Lead Refills

Pentel C5052HBX Hi-Polymer lead refills supply 0.5 mm fine 2H graphite for mechanical pencils. Each stick writes as far as a full wooden pencil while delivering crisp, consistent darkness. The super-strong formulation resists breakage during regular writing and drafting tasks. A box contains 144 leads in a 12-piece pack configuration.

Compatibility Check Before Ordering

Verify that your mechanical pencil accepts 0.5 mm diameter leads before purchasing. Confirm the 2H hardness grade matches your preferred line weight and darkness for the intended application. Ensure the refill length suits the pencil’s internal reservoir or cassette design.

Upgrade From Standard Leads

These Hi-Polymer refills replace conventional graphite leads that snap frequently or produce uneven lines. The jump is worth it when you need reliable, uniform strokes for technical drawing, extended note-taking or everyday writing. Buyers who require thicker line widths or softer grades should select a different specification.

Questions about this item

Does the box contain the mechanical pencil or only the 144 leads?

Only the 144 Hi-Polymer 2H leads are supplied; a compatible 0.5 mm mechanical pencil must be purchased separately.

Why choose the 2H grade over HB or B options?

2H gives a harder, lighter line that holds a sharp point longer, ideal for precise technical drawings and light writing pressure.

What does the 0.5 mm diameter mean for everyday use?

It fits standard 0.5 mm mechanical pencils and produces a fine line suited to detailed notes, diagrams and small handwriting.
