Engineered with ultra-fine 0.3mm lead capability, this pencil is designed for intricate technical drawings, compact planners, fine calligraphy, and detailed mathematical calculations. It incorporates Tombow's acclaimed dual-action lead feed system: simply shake the pencil gently to advance the 0.3mm lead without breaking your writing stride, or press the pocket clip downward. For secure storage, sliding the clip upward locks the internal shaker weight, preventing unwanted lead extension in cases or bags.\u003c\/p\u003e\n\u003cp\u003eA fixed 4mm metallic drafting sleeve delivers an unobstructed view of the writing surface and aligns cleanly against rulers and templates. Crowned at the top of the skeleton barrel is a full-length, refillable twist-up Tombow MONO eraser offering roughly 1.8cm of premium, non-abrasive erasing compound. With a matte-textured translucent grip and balanced weight distribution, the Clear Purple Mono Graph delivers supreme control and clarity for detail-oriented writing.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-Action Lead Advancement:\u003c\/strong\u003e Shake the pencil vertically to feed lead effortlessly, or press the pocket clip down for traditional click advance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShake-Lock Safety Clip:\u003c\/strong\u003e Push the clip upward to lock the shaker weight and prevent accidental lead extension during transport.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefillable Twist-Up MONO Eraser:\u003c\/strong\u003e Integrated high-grade Tombow MONO vinyl eraser extends and retracts smoothly with a twist of the top collar.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4mm Precision Drafting Sleeve:\u003c\/strong\u003e Fixed metallic guide pipe ensures superior visibility against rulers, templates, and drafting straightedges.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClear Skeleton Purple Finish:\u003c\/strong\u003e Translucent purple barrel reveals the internal shaker mechanism and adds modern Japanese styling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Tombow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Mono Graph Clear Color Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e DPA-139F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Color:\u003c\/strong\u003e Clear Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Diameter:\u003c\/strong\u003e 0.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMechanism:\u003c\/strong\u003e Shaker Mechanism \u0026amp; Clip Knock Mechanism with Shake-Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGuide Pipe Length:\u003c\/strong\u003e 4.0 mm fixed sleeve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEraser Component:\u003c\/strong\u003e Twist-up MONO eraser (Refill model: ER-MG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHow does the shaker lead advance work on the Mono Graph?\u003c\/strong\u003e\n  Inside the pencil barrel is an internal brass weight. A gentle vertical shake slides the weight down against the clutch mechanism, extending the 0.3mm lead without shifting your hand grip.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHow do I prevent the pencil from extending lead inside my bag?\u003c\/strong\u003e\n  Push the pocket clip upward until it clicks into the locked position. This disengages the shaker weight so movement during travel will not feed lead.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCan I advance the lead using the clip instead of shaking?\u003c\/strong\u003e\n  Yes, pressing the pocket clip downward functions as a standard push-button click mechanism to advance the lead normally.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWhat eraser refills fit this pencil?\u003c\/strong\u003e\n  This pencil utilizes authentic Tombow ER-MG replacement erasers.
