Lead core

First determine the pencil type you use—mechanical leads versus wood pencils—and the required hardness. The listing includes HB, 2B, and HI-POLYMER leads from brands like Stabilo, Pentel, and MG, which cover drawing, sketching, and drafting tasks. Choose HB for general writing, 2B for expressive shading, and specialized HI-POLYMER leads for smoother, consistent marks. Ensure the lead size matches your pencil’s mechanism.

HB sits in the middle of hardness, suitable for everyday writing and light sketching, while 2B is softer and produces darker lines ideal for shading. HI-POLYMER leads offer superior smoothness and break resistance for technical drawing and precise lines. The choices come from brands like Pentel and Stabilo, so pick according to your drawing style, desired hardness, and the pencil system you own.

For technical drawing, HI-POLYMER or harder leads maintain clean, precise lines and reduce smudging. For casual writing or sketching, HB or 2B provides a wider range of tonal options and easier shading. The listed items cover both mechanical-pencil-leads and wood-lead accessories, giving you flexible options to match your workflow and preferred pencil type.

First remove the old lead by gently pulling from the mouthpiece or feeder tube. Then insert a new piece of lead of the correct thickness, typically 0.5 mm or 0.7 mm, until it reaches the mechanism’s stop. Test by clicking gently to extend the lead. Always use the recommended lead size for your pencil to avoid jams or breaks.

Brand choices such as Stabilo, Pentel, and MG are well-known for consistent lead quality and compatibility across multiple pencil styles. When selecting, verify your pencil’s lead size and type, and ensure the leads are designed for your mechanism. This helps you maintain smooth performance and avoids common issues like lead wobble or breakage.
