{"product_id":"caran-dache-technograph-3-mm-leads-6-pack","title":"Caran d'Ache Technograph 3 mm leads 6-pack","description":"The Caran d'Ache Technograph 3mm refill leads are premium replacement graphite leads for the Fixpencil 3mm clutch pencil and any standard 3mm lead holder. Each lead is formulated with high-density extra-pure refined Swiss graphite, engineered to minimize crumbling while delivering consistent, uniform line quality from first stroke to last. The extra-thick 3mm diameter provides strong break-resistance under sustained drawing pressure and produces a bolder, broader mark suited to expressive studio work, large-format drawing, and confident layout sketching.\u003cbr\u003e\u003cbr\u003eAvailable in three grades covering a wide range of applications. HB is the balanced universal grade for general studio layout, product sketching, and daily note-taking. 3B is a soft, richly saturated grade that blends freely for portrait shading, tonal gradient work, and bold architectural layouts. 6B is the softest and darkest grade in the range — an ultra-expressive lead for life drawing, deep shadow coverage, gestural sketching, and dramatic value building at scale. Six leads per pack, each 120mm long.\u003cbr\u003e\u003cbr\u003eSpecifications\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eAvailable grades: HB, 3B, 6B\u003c\/li\u003e\n\u003cli\u003eLead diameter: 3.0 mm\u003c\/li\u003e\n\u003cli\u003eLead length: 120 mm\u003c\/li\u003e\n\u003cli\u003ePack contents: 6 leads\u003c\/li\u003e\n\u003cli\u003eComposition: High-density extra-pure refined Swiss graphite\u003c\/li\u003e\n\u003cli\u003eCompatibility: Caran d'Ache Fixpencil 3mm and all standard 3mm lead holders\u003c\/li\u003e\n\u003cli\u003ePackaging: Compact protective storage pack\u003c\/li\u003e\n\u003cli\u003eOrigin: Swiss Made, Geneva\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003eFAQ\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhich grade should I choose?\u003c\/strong\u003e HB suits general layout work, note-taking, and studio wireframes. 3B is the choice for portrait shading, tonal drawing, and expressive line work where blendability matters. 6B is for maximum darkness and gestural freedom — life drawing, deep shadow rendering, and large-format expressive work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is the 3mm format best suited for?\u003c\/strong\u003e The 3mm diameter produces a broader, bolder mark than finer lead formats — well suited for expressive studio work, large-format drawing, and confident gestural sketching where a wider line and stronger break-resistance are the priority.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAre these compatible with lead holders other than the Fixpencil?\u003c\/strong\u003e Yes.
