Pentel Super Hi-Polymer Lead Refills deliver crisp, dark lines with consistent density for 0.7mm mechanical pencils. This Costco value pack includes 3 tubes with 30 leads each, for a total of 90 individual lead pieces. HB hardness is equivalent to a No. 2 wooden pencil and is the standard for everyday writing and standardized testing.

Pentel's patented Super Hi-Polymer formula provides superior strength with minimal breakage compared to standard lead. Each lead writes as far as an entire wooden pencil, producing smooth, dark lines suitable for faxing, photocopying, and electronic scanning. The lead is fully erasable and compatible with most 0.7mm refillable automatic pencils.
