Ideal for fine-line writing and drafting

This Pentel C505HBBX refill pack supplies 144 pieces of 0.5 mm black lead. The Super Hi-Polymer formulation delivers crisp lines of consistent darkness, smoothness and density. Each lead writes as far as an entire wooden pencil, so a single box replaces many traditional pencils.

Suited to students, engineers and daily note-takers

Writers who need broad strokes for shading or bold markup should choose a larger diameter. The fine point and hard polymer feel may also feel too stiff for artists who prefer softer, expressive grades.

The deciding spec is 0.5 mm diameter

Only mechanical pencils that accept 0.5 mm leads can use these refills. The pack contains 144 leads packaged in 12-piece tubes, providing long-lasting supply for compatible instruments.

Questions about this item

How many 0.5 mm leads are in the box before I need to reorder?

The box contains 144 leads, so reordering depends on how quickly you use them.

Does the 0.5 mm diameter limit how long I can write continuously?

Each super-strong lead writes as far as an entire wooden pencil, so the diameter itself does not limit writing time.

Will the leads create dust or heat in the pencil during all-day use?

Super Hi-Polymer formulation produces crisp lines with consistent density and smoothness, leaving minimal residue and no heat.
