Uni Kuru Toga Pipe Slide Mechanical Pencil

Uni Kuru Toga Pipe Slide Mechanical Pencil

The Uni Kuru Toga Pipe Slide Model (M5-452) elevates drafting and note-taking with Mitsubishi Pencil's iconic rotating gear technology paired with a dynamic sliding lead sleeve. As you write, internal gears twist the 0.5mm lead incrementally with every stroke to maintain a conical, ultra-sharp point without flattening or smudging. The retractable guide pipe glides smoothly back as the core wears down, shielding delicate lead from excess writing pressure and virtually eliminating lead breakage.

Key Features

• Auto-Rotating Lead Engine: Patented Kuru Toga mechanism turns the lead fractionally on every lift, ensuring crisp, uniform line width without chisel-edge dulling.
• Sliding Guide Pipe System: Protective guide pipe recedes alongside lead consumption, preventing snaps during rapid writing and extending intervals between clicks.
• Full Sleeve Retractability: Retract the entire metallic sleeve inside the cone tip when not in use for pocket-safe portability without snagging clothing.
• Ergonomic Lightweight Barrel: Balanced resin casing features a translucent viewing window into the turning gear mechanism and a contoured grip for fatigue-free sessions.
• Concealed Eraser & Sturdy Clip: Includes a replaceable push-button eraser beneath a protective top cap and a durable clip for notebook attachment.

Frequently Asked Questions

• How does the Pipe Slide mechanism prevent lead breakage?
  The sliding guide pipe shields the lead right down to the paper surface, sliding back automatically as you write so the lead never extends far enough to snap under pressure.
• How does the Kuru Toga rotating lead technology work?
  A three-gear clutch inside the pencil engages every time the pencil lifts from the paper, rotating the lead slightly to wear it down into an even, continuous cone.
• Can the metal guide pipe be retracted for pocket safety?
  Yes, holding down the top push button while pressing the tip against a flat surface fully retracts the sleeve into the barrel.
• What type of lead is compatible with this mechanical pencil?
  It accommodates any standard 0.5mm pencil lead, though Uni NanoDia or Kuru Toga smudge-proof leads provide optimal rotation performance.
• Is the eraser refillable?
  Yes, the eraser under the cap can be replaced with standard Uni mechanical pencil eraser refills.
