## Long description

Set of 6 KOH-I-NOOR graphite lead refills with 2.5 mm diameter designed for use in mechanical clutch pencils and holders. These leads deliver a consistent medium-thick line suitable for technical drawing, sketching and everyday writing. Manufactured to provide uniform laydown and good break resistance, the set is intended for both students and professionals who require reliable graphite performance in 2.5 mm format.
Advantages
The 2.5 mm leads offer stable line width and even graphite distribution across the stroke, reducing the need for frequent sharpening. A pack of six ensures extended use and convenient replacement cycles for busy projects. Compatibility with standard 2.5 mm clutch pencils and holders allows quick interchange without special adapters. The leads combine mechanical strength with smooth application to reduce crumbling and interruptions during work.

Key specifications
 Diameter: 2.5 mm
 Quantity: 6 leads per set
 Material: graphite
 Line thickness: medium (consistent medium-thick strokes)
 Compatibility: fits 2.5 mm clutch pencils and holders
How to use
Insert a single lead into the barrel of a compatible 2.5 mm clutch pencil or holder following the tool manufacturer’s instructions. Advance the lead by operating the clutch mechanism to expose the desired length; retract or replace the lead when blunt or broken. For consistent results, hold the pencil at an angle appropriate to the task—more upright for precise lines, lower angle for broader shading. Store unused leads in a protective case to prevent breakage and contamination.
Usage recommendations
Use the KOH-I-NOOR 2.5 mm leads for tasks requiring medium-thick, uniform lines. Replace leads before they become very short to avoid jamming the clutch mechanism and keep a spare set available for uninterrupted work. When shading or blending, pair with suitable erasers and blending tools to maintain clean results.
