Mechanical pencil leads BIC Criterium 550 refill, green, 1.5 mm, pack of 12

Pack of 12 BIC Criterium 550 refill leads in green colour, designed as replacement leads for mechanical pencils that accept 1.5 mm refills. These leads provide a thicker line suitable for drafting, sketching and everyday writing where a more robust stroke is required. The compact packaging keeps leads protected and easy to carry in a pencil case or bag.

Advantages

These 1.5 mm green leads offer consistent laydown and are suitable for use in compatible BIC Criterium mechanical pencils. The thicker diameter reduces breakage compared with thinner leads when applying moderate pressure, and the green colour allows visible, non-graphite marking for diagrams, colour coding and creative tasks. The pack of 12 refills ensures a practical supply for regular use and the small, sealed container protects leads from damage during transport.

Suitable for

• Technical drawing and rough sketches requiring thicker lines
• Everyday writing where a bold non-graphite colour is helpful
• Colour-coding notes, diagrams or draft plans
• Students and professionals using 1.5 mm mechanical pencils

How to use

Open the sealed container and remove a single refill lead. Insert the lead into the barrel of a compatible mechanical pencil following the pencil manufacturer’s instructions for loading 1.5 mm refills. Advance the lead as needed for writing or drawing. When the lead is consumed or broken, repeat the loading process with a new refill. Store unused leads in the original container to keep them protected from bending or contamination.

Usage recommendations

For best results, use these 1.5 mm leads in mechanical pencils that specify compatibility with thicker refills and avoid applying excessive lateral pressure to minimise breakage. Keep the container closed when not in use to protect leads and maintain consistent performance.
