The 7B lead grade is specifically formulated to leave clear, dark, and highly visible marks that remain legible throughout the working process, ensuring accuracy in professional glazing, tiling, and construction projects.

Advantages

This marking pencil offers exceptional reliability for professionals who require consistent performance on challenging surfaces. The soft 7B lead allows for smooth application without scratching or damaging delicate materials like glass or polished ceramic. With a bulk pack of 100 pieces, users benefit from a long-lasting supply that is perfect for high-volume environments, reducing the need for frequent replacements and ensuring that a sharp, effective marking tool is always at hand.

Suitable for

• Marking cut lines on glass sheets
• Layout work on ceramic and porcelain tiles
• Temporary labeling on smooth metal or plastic surfaces
• Professional glazing and window installation tasks
• Construction site measurements on polished materials

When it may not be suitable

This pencil is not intended for use on porous surfaces like raw wood, paper, or unglazed concrete, as the specialized lead may not adhere correctly or provide the desired line quality. It is also not suitable for applications requiring permanent, waterproof markings that must withstand harsh chemical solvents or extreme outdoor weathering.

Key specifications

• Length: 240mm
• Lead grade: 7B
• Quantity: 100 pieces
• Surface compatibility: Glass, ceramic, glazed tiles

How to use

To achieve the best results, ensure the surface is clean, dry, and free from dust or grease before marking. Apply light pressure to the pencil to create the desired line; the soft 7B lead is designed to transfer easily to smooth surfaces without requiring heavy force. If the tip becomes dull, use a standard pencil sharpener to restore the point for continued precision. Marks can typically be removed from glass and ceramic surfaces using a dry cloth or a mild cleaning agent.

What to consider before purchase

• Verify that the 7B lead softness meets your specific marking requirements
• Ensure the surface material is smooth and non-porous for optimal performance
• Consider the storage space required for a 100-piece bulk pack

Usage recommendations

For optimal longevity and performance, store the pencils in a cool, dry place away from direct heat sources. Always keep the tips sharpened to maintain the highest level of accuracy during detailed layout work.
