Pentel of America, Ltd. C27HBBX 0.7mm Black Lead Refill 360 Pack

360-count 0.7mm lead refill pack

This Pentel C27HBBX box contains 360 pieces of 0.7mm black Super Hi-Polymer lead. It suits students, drafters and office workers who use mechanical pencils daily and want a single bulk purchase to last through heavy writing or drawing sessions. Each stick is engineered for consistent darkness and smoothness across the whole pack.

Replaces frequent small-tube purchases

Twelve leads in a tube match the writing distance of twelve wooden pencils, so the 360-count box replaces thirty of those tubes. The jump is worth it when you go through leads quickly and want to avoid re-ordering every few weeks. It is not for users who only need a few spares or who prefer softer or harder grades not offered here.

Simple drop-in loading

Leads feed straight into any mechanical pencil that accepts 0.7mm diameter refills; no tools or adjustments are required. The only common issue is jamming if a bent piece is inserted or if the pencil’s clutch is worn, so discard damaged sticks and check the mechanism if feeding becomes unreliable.
