Mechanical pencil leads Tetis KC001-B triangular 0.7 mm 12 pieces

Tetis KC001-B triangular 0.7 mm mechanical pencil leads, supplied in a compact pack of 12, are replacement graphite cores intended for mechanical pencils that accept triangular leads. These 0.7 mm leads provide a consistent medium-width line suitable for general writing, sketching and technical drawing. The triangular cross-section improves grip and prevents rolling, supporting stable handling during extended use and convenient storage for classroom, office or field work.

Advantages

The triangular shape of these leads offers improved positional stability in compatible pencil mechanisms and reduces unwanted rotation. A 0.7 mm diameter balances precision and durability, giving a steady line without frequent breakage under normal writing pressure. The small, lightweight pack of 12 cores is easy to carry and store, ensuring a ready supply of replacement leads for regular use.

Suitable for

• Everyday note taking and handwriting
• Sketching and preliminary illustrations
• Technical drawing and draft work requiring consistent medium lines
• Use in schools, offices and on-site tasks where compact spare leads are useful

Key specifications

• Lead shape: triangular cross-section for non-rolling grip
• Lead diameter: 0.7 mm for medium-width lines
• Material: graphite core suitable for writing and drawing
• Pack size: 12 replacement leads per pack

How to use

Open the packaging and load the leads into a compatible 0.7 mm mechanical pencil designed for triangular cores. Advance the lead gently according to the pencil mechanism and apply moderate pressure when writing or drawing to avoid breakage. When the visible lead shortens, replace with a fresh core from the pack. Store unused leads in their original container to protect them from dust and breakage.

Usage recommendations

For longer-lasting performance, use moderate writing pressure and retract the lead when carrying the pencil. Verify pencil compatibility with triangular leads before insertion; if compatibility is uncertain, test a single lead first to ensure smooth feeding.
