Uni Kuru Toga Pipe Slide Mechanical Pencil

Uni Kuru Toga Pipe Slide Mechanical Pencil

The Uni Kuru Toga Pipe Slide Mechanical Pencil combines Mitsubishi Pencil's patented auto-rotating lead engine with an advanced break-resistant sliding pipe guide sleeve. Precision-crafted in Japan, this high-performance 0.5mm mechanical pencil continuously rotates the internal graphite core with every stroke, maintaining a perpetually conical sharp point for crisp, smudge-free lines and even line density. Finished in a professional translucent smoke black barrel, it delivers an optimal balance of Japanese engineering, writing precision, and everyday durability.

Key Features

• Auto-Rotating Kuru Toga Engine: Internal gear incrementally rotates the 0.5mm lead as you write, preventing flat spots and uneven line thickness.
• Sliding Pipe Guide Sleeve: Retractable metal guide pipe cushions the lead under pressure and recedes smoothly as the core wears down.
• Clean 0.5mm Line Clarity: Produces consistently sharp, uniform writing with reduced graphite dust and zero page smudging.
• Translucent Smoke Black Casing: Sleek black barrel features an integrated viewing window showing the inner rotating mechanism at work.
• Concealed Quality Eraser: Built-in spot eraser sits beneath the top push-button cap for swift, convenient corrections.

Frequently Asked Questions

• How does the Kuru Toga rotation mechanism work? Each time the pencil tip touches and leaves the paper, internal gears rotate the lead approximately 9 degrees to maintain an evenly sharpened point.
• What does the Pipe Slide system do? The protective metal pipe recedes gradually into the tip as the lead shortens, allowing continuous writing without constantly clicking to advance more lead.
• Can the metal guide sleeve be fully retracted? Yes, depressing the top click button and pushing the tip against a flat surface retracts the metal pipe completely for pocket safety.
• What type of lead refills should I use? It accepts all standard 0.5mm mechanical pencil lead refills, with Uni Kuru Toga leads recommended for optimal rotating performance.
• Is the built-in eraser replaceable? Yes, the spot eraser under the push cap can be easily replaced with standard Uni mechanical pencil eraser refills.
