Uni Kuru Toga Advance Auto Lead Rotating Mechanical Pencil with Leads

The Uni Kuru Toga Advance M5-559 is a 0.5mm mechanical pencil with automatic lead rotation and included Nano Dia leads. Its W-Speed engine rotates the lead as you write and lift the tip from the paper, helping it wear more evenly for a consistently fine point. A sliding metal lead sleeve helps protect the lead during writing.

Key Features

• Automatic lead rotation: A spring-loaded clutch turns the lead incrementally when you lift the pencil from the page, helping reduce uneven wear and flattened edges.
• W-Speed engine: Rotates the lead twice as fast as the original Uni Kuru Toga mechanism, completing a rotation in approximately 20 writing strokes.
• 0.5mm lead size: Suited to everyday handwriting, study notes, planner entries and detailed work.
• Sliding metal sleeve: Supports the exposed lead to help reduce breakage and retracts as you write.
• Nano Dia leads included: The lead formulation contains nanodiamond particles and silicone oil for strength and smooth, dark lines.
• Limited-edition design options: Choose from the listed themed barrel options to personalise your stationery collection.

Frequently Asked Questions

What lead size does this pencil use?

This M5-559 version uses 0.5mm lead. Choose replacement leads with the same diameter.

How does the automatic lead rotation work?

The mechanism turns the lead a small amount when you lift the pencil from the paper between strokes. This helps distribute wear around the lead rather than letting one side become flat.

What is different about the W-Speed engine?

It rotates the lead twice as fast as the original Uni Kuru Toga mechanism, completing a full rotation in approximately 20 writing strokes. Performance depends on the way you write and lift the tip.

Does the metal sleeve prevent all lead breakage?

No. The sleeve supports the lead to help reduce breakage and retracts as you write, but excessive pressure or overextended lead can still cause it to break.

Are replacement leads included?

Yes. This listing includes Nano Dia leads with the pencil. The lead quantity and hardness grade are not specified in the current product information.

Which designs can I choose?

The listed options are Coffee Frappe, Labrador, Caramel Pudding, Blue Flower, Pink Donuts and Rabbit. Select your preferred design from the product options, subject to availability.

What are Nano Dia leads?

Nano Dia leads contain nanodiamond particles and silicone oil. The formulation is designed to combine lead strength with smooth, dark writing.
