Pentel 0.7 mm B Lead Refills

Pentel 50-B Super Hi-Polymer lead refills supply 0.7 mm diameter graphite in B hardness for mechanical pencils. The tube holds twelve black leads, each 60 mm long. The patented polymer formula increases strength and produces a darker line with minimal breakage. Students and professionals who write or draw with 0.7 mm pencils can use this pack for daily work.

Suited for 0.7 mm mechanical pencils

These refills fit any mechanical pencil that accepts 0.7 mm B leads. The darker imprint works well for drawing, while lighter pressure suits drafting and template tasks. HB-equivalent density guarantees accurate scanning on standardised tests and forms. Writers who need a different hardness or diameter should choose a separate refill pack.

Guaranteed to scan on tests

The lead formulation meets scanning requirements for machine-readable answer sheets and documents. Proprietary Super Hi-Polymer material resists snapping during normal writing pressure. Each tube provides twelve leads, giving extended use before another refill is required. Users who rely on optical-mark recognition can trust consistent readability.

Questions about this item

How dark will the 0.7mm B leads actually write on paper?

The B grade produces a darker line than HB, making it well suited for drawing or bold writing while still scanning reliably on test forms.

Will these 0.7mm refills work in any mechanical pencil I own?

They fit any mechanical pencil that accepts standard 0.7mm diameter lead, which is the most common size for school and office models.

How long is each lead stick so I know how many refills I get per tube?

Each stick measures 60mm, and with 12 sticks per tube you have plenty of writing length before needing another pack.
