Engineered in Japan by Mitsubishi Pencil, each lead core is infused with roughly 400 million nano-diamond particles, providing exceptional tensile strength that withstands heavy drafting pressure without snapping. The 4H hardness grade produces razor-thin, light grey guidelines that will not smudge under rulers, making it the premier choice for blueprint plotting, precision schematics, and watercolor under-sketching.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNano-Diamond Infused Matrix:\u003c\/strong\u003e Advanced nanotechnology reinforces core cohesion, eliminating lead breakage on dense drafting vellum and paper.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtra-Hard 4H Grade:\u003c\/strong\u003e Delivers ultra-crisp, light, high-precision line work that holds a pointed edge for extended drafting sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% Smudge-Proof Performance:\u003c\/strong\u003e Hard graphite formula leaves zero residual powder, keeping hands, rulers, and drafting tables clean.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtective Slide Dispenser:\u003c\/strong\u003e Ergonomic sliding case dispenses a single 0.5mm lead smoothly while shielding remaining stock from impact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Value 80-Lead Set:\u003c\/strong\u003e Contains 2 individual dispenser tubes with 40 leads each (80 leads total) for continuous professional drafting.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Uni\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e NanoDia Low-Wear Leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e U05202ND-4H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Diameter:\u003c\/strong\u003e 0.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Grade:\u003c\/strong\u003e 4H (Extra Hard \/ Technical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 80 Leads (2 Packs of 40 Leads)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Length:\u003c\/strong\u003e 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Japan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is 4H pencil lead typically used for?\u003c\/strong\u003e 4H is an extra-hard grade engineered for technical drafting, architectural layouts, engineering drawings, and faint initial sketch lines that need to erase cleanly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWill 4H lead scratch delicate drawing paper?\u003c\/strong\u003e No, despite its extreme hardness, the nano-diamond and lubricant formula ensures a smooth glide without gouging paper fibers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs this refill compatible with standard 0.5mm mechanical pencils?\u003c\/strong\u003e Yes, it fits all standard 0.5mm mechanical pencils, including Uni Kuru Toga, Staedtler, Pentel, and Rotring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes 4H lead smudge when erased or washed over?\u003c\/strong\u003e 4H graphite produces minimal dust and adheres tightly, making it ideal for guidelines underneath ink lines or watercolor washes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow many total leads are provided?\u003c\/strong\u003e The bundle includes 2 tubes containing 40 leads each, providing 80 total 0.5mm 4H leads.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Uni","offers":[{"title":"Default Title","offer_id":47485535485986,"sku":"UNI-LEAD-U05202ND4H","price":10.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0902\/3045\/6354\/files\/ND-05-4H.jpg?v=1789008751","url":"https:\/\/www.xypen.com\/products\/uni-nanodia-05mm-4h-pencil-lead-2-pack","provider":"XYPen","version":"1.0","type":"link"}
