Pentel PENC505HB 0.5mm Hb Lead Refills 12 Piece

Product Description

The PENTEL PENC505HB is a 12-piece tube of Super Hi-Polymer lead refills engineered for mechanical pencils. Sized at 0.5mm diameter with an HB hardness rating, these leads deliver consistent line darkness, smooth feed, and reliable density for precision writing and drafting work. The formulation resists breakage during normal use, reducing interruptions on the job. Writing capacity per tube is equivalent to 12 standard wooden pencils, making this a practical bulk-refill option for professionals who depend on mechanical pencils for marking, sketching, or notation tasks throughout the workday.

These lead refills are suited for any mechanical pencil that accepts 0.5mm leads, making them a versatile consumable for office environments, job sites, and technical drawing applications. Their consistent HB hardness produces a medium-dark line appropriate for general notation, form completion, and light drafting. Packaged in a tube of 12 pieces, the PENC505HB is sold by the tube and fits the needs of tradespeople, estimators, and field technicians who regularly cycle through lead refills.
