Pentel 0.7 mm HB Lead Refill — 144 pieces

This Pentel Super Hi-Polymer lead refill supplies 144 pieces of 0.7 mm HB graphite in a single box. The formulation is engineered for consistent darkness, smoothness and density in mechanical pencils. Each lead is designed to write as far as an entire wooden pencil. The pack suits students, office workers and draughtspeople who want a long-lasting, uniform line.

Suited for 0.7 mm mechanical pencils needing HB

The refill fits any mechanical pencil that accepts 0.7 mm HB leads and is ideal for everyday writing, note-taking and technical sketching. It will not work in pencils that require 0.5 mm or other diameters, nor for users who prefer softer or harder grades such as B or H. Buyers who need coloured leads or larger bulk packs should look at alternative SKUs.

144-piece box quantity decides value and storage

The box contains exactly 144 leads, delivered as twelve 12-piece tubes. This quantity determines how often you reorder and how much drawer space the supply occupies. If your usage is light, a smaller pack may be more practical; if you run a classroom or high-volume office, the 144-count box reduces replenishment frequency.
