{"product_id":"koh-i-noor-rapidograph-technical-pens-no-3165","title":"Rapidograph Technical Pens No. 3165","description":"\u003cp\u003eTechnical drawing demands pens that start immediately and maintain unwavering line width through entire projects. Rapidograph pens deliver both through airtight double-seal caps that prevent ink from drying between uses, no priming, no false starts, just consistent flow from first stroke. See-through cartridges let you monitor ink levels during work, while metric point designations in millimeters correspond directly to line widths in technical drawings, simplifying the task of matching specifications across scaled reproductions.\u003c\/p\u003e\n\u003cp\u003eNine calibrated widths accommodate everything from fine detail work to bold border lines, with each maintaining its designated width through extended use. The precision-engineered points work with lettering guides and templates, essential for standardized technical documentation. Stainless steel replacement points extend the pen's working life indefinitely; when a point wears or clogs, replace it rather than discarding the entire pen.\u003c\/p\u003e\n\u003cp\u003eEach pen includes point, holder, cap, and empty cartridge ready for Koh-I-Noor technical inks. Architects, engineers, and illustrators who need reliable line quality across multi-sheet projects keep multiple widths ready for immediate deployment.\u003c\/p\u003e","brand":"Koh-I-Noor","offers":[{"title":"0.35 mm","offer_id":47977162113253,"sku":"17907","price":38.54,"currency_code":"USD","in_stock":false},{"title":"0.13 mm","offer_id":47977162146021,"sku":"18505","price":44.78,"currency_code":"USD","in_stock":false},{"title":"0.18 mm","offer_id":47977162178789,"sku":"24339","price":41.41,"currency_code":"USD","in_stock":true},{"title":"0.25 mm","offer_id":47977162211557,"sku":"25106","price":38.54,"currency_code":"USD","in_stock":true},{"title":"0.70 mm","offer_id":47977162244325,"sku":"26228","price":38.54,"currency_code":"USD","in_stock":true},{"title":"0.80 mm","offer_id":47977162277093,"sku":"46404","price":38.54,"currency_code":"USD","in_stock":true},{"title":"0.50 mm","offer_id":47977162309861,"sku":"53290","price":38.54,"currency_code":"USD","in_stock":false},{"title":"0.60 mm","offer_id":47977162342629,"sku":"66161","price":38.54,"currency_code":"USD","in_stock":true},{"title":"1.20 mm","offer_id":47977162375397,"sku":"74650","price":38.54,"currency_code":"USD","in_stock":true},{"title":"0.30 mm","offer_id":47977162408165,"sku":"80129","price":38.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s17907.jpg?v=1770338496","url":"https:\/\/www.texasart.mom\/products\/koh-i-noor-rapidograph-technical-pens-no-3165","provider":"Texas Art Supply","version":"1.0","type":"link"}
