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.

Questions about this item

What mechanical pencils accept the 0.7 mm diameter leads in this box?

Any mechanical pencil designed for 0.7 mm lead will accept these refills.

How do I load the 12 leads from each tube into my pencil without jamming?

Open the pencil's lead sleeve, drop the leads in one at a time, then advance the mechanism slowly until the first lead grips.

How many of the 360 leads will I use before the eraser on my pencil wears out?

Each lead writes as far as a whole wooden pencil, so the 360-count box typically outlasts several erasers.
