The Tombow MONO Graph Fine mechanical pencil elevates technical precision to an art form. Engineered for architects, designers, and discerning writers, it features an integrated one-piece grip-and-cone construction that completely eliminates tip wobble.

Key Features

• Integrated Nose and Grip Section: Machined metal tip seamlessly unified with the grip eliminates play, rattling, and microscopic movement for laser-precise linework.
• Wide-Angle Drafting View: Tapered stepped-cone tip provides an unobstructed panoramic view of the paper, making it effortless to trace against rulers and templates.
• Ergonomic Soft-Touch Metal Grip: Coated in a specialized velvety soft-touch texture that ensures a secure, slip-resistant hold without uncomfortable ridges or abrasive knurling.
• Lock-on-Inversion Eraser Mechanism: Internal gravity mechanism automatically locks the knock mechanism when inverted, preventing accidental lead extension while erasing.

Frequently Asked Questions

How does the eraser lock work?

When you turn the pencil upside down to erase, an internal weight activates the eraser lock so you can press down firmly to erase without accidentally clicking and advancing more lead.

How do I refill the eraser?

Twist the eraser knob clockwise until the depleted eraser is fully raised, gently pull it out, insert a replacement Tombow ER-MGL eraser, and twist counterclockwise to seat it.

How do I refill the pencil lead?

Gently pull the eraser unit straight off from the top of the barrel to access the internal lead storage tube, insert up to three replacement leads, and press the eraser unit back in.

What makes the MONO Graph Fine different from the standard MONO Graph?

The Fine edition features a solid integrated metal tip-and-grip assembly to eliminate wobble, a slimmer 3.6mm detail eraser, and a refined soft-touch tactile finish rather than a shaker mechanism.

Can this pencil be used with drafting rulers and compasses?

Yes, the precision stepped 4mm drafting sleeve is designed specifically to align smoothly against rulers, set squares, and architectural stencils.
