## Long description

Polymer Leads 1.0 HB by rOtring are high-polymer graphite refills designed for mechanical pencils. These 1.0 HB fine leads provide consistent line quality and reliable performance for writing and technical drawing. Packaged as spare leads, they are compatible with mechanical pencils that accept 1.0 mm refills and aim to deliver smooth, even marks with reduced breakage compared to standard leads.
Advantages
High-polymer composition increases strength and reduces the frequency of breakage, while the HB hardness balances darkness and durability for general-purpose use. The fine 1.0 mm diameter offers precise lines suitable for detailed sketches, notes, and technical work. rOtring manufacturing standards help ensure uniform diameter and consistent quality across refills.
