{"product_id":"diplomat-cobra-matte-black-guilloche-rollerball-pen","title":"Diplomat Cobra Rollerball Pen - Matte Black","description":"\u003cp\u003eThe Diplomat Cobra Rollerball Pen - Matte Black Guilloche pairs a bold reptile-inspired texture with the smooth convenience of a capped liquid-ink writing system. Deeply engraved scales travel across the matte black metal body, while polished black PVD trim keeps the design unified and contemporary.\u003c\/p\u003e\n \n \u003ch2\u003eDesigned to Be Felt\u003c\/h2\u003e\n \n \u003cp\u003eThe Cobra's guilloche pattern is cut deeply enough to provide both visual movement and tactile feedback. Its scale-like surface improves grip and gives the pen a more physical presence than a conventional smooth lacquered rollerball.\u003c\/p\u003e\n \n \u003cp\u003eBeveled top and bottom finials add structure to the silhouette, while the matte black finish reduces glare and allows the engraved pattern to remain the central feature.\u003c\/p\u003e\n \n \u003ch2\u003eMagnetic Cap\u003c\/h2\u003e\n \n \u003cp\u003eThe magnetic cap opens and closes with a quick, precise action, making the pen especially practical for meetings, notes, and everyday desk use. It may be posted securely on the barrel for additional length and balance.\u003c\/p\u003e\n \n \u003ch2\u003eWriting Experience\u003c\/h2\u003e\n \n \u003cp\u003eThe rollerball refill produces a smooth, fluid line with less pressure than a traditional ballpoint. Its metal construction and textured grip provide stable control, while the capped format protects the writing tip between uses.\u003c\/p\u003e\n \n \u003ch2\u003eCollector Perspective\u003c\/h2\u003e\n \n \u003cp\u003eThe Matte Black Cobra rollerball preserves the strongest design elements of the fountain pen while offering a more immediately accessible writing system. It is especially appealing as part of a matching set because the scale pattern and dark PVD details remain consistent across formats.\u003c\/p\u003e\n \n \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n \n \u003cul\u003e\n \u003cli\u003eProduct Type: Rollerball Pen\u003c\/li\u003e\n \u003cli\u003eCollection: Diplomat Cobra\u003c\/li\u003e\n \u003cli\u003eFinish: Matte Black Guilloche\u003c\/li\u003e\n \u003cli\u003eBody Material: Metal\u003c\/li\u003e\n \u003cli\u003eSurface Treatment: Deep cobra-scale guilloche engraving\u003c\/li\u003e\n \u003cli\u003eTrim: Polished black PVD\u003c\/li\u003e\n \u003cli\u003eCap: Magnetic and postable\u003c\/li\u003e\n \u003cli\u003eRefill Type: Diplomat-compatible rollerball refill\u003c\/li\u003e\n \u003cli\u003eApproximate Length: 5.6 inches\u003c\/li\u003e\n \u003cli\u003eApproximate Diameter: 0.6 inches\u003c\/li\u003e\n \u003cli\u003ePrimary Color: Black\u003c\/li\u003e\n \u003cli\u003eCountry of Origin: Germany\u003c\/li\u003e\n \u003c\/ul\u003e","brand":"Diplomat","offers":[{"title":"Default Title","offer_id":54521185829139,"sku":"D41401030","price":132.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/6627\/files\/Diplomat-Cobra-Rollerball-Pen-Matte-Black-uncapped-leaning.jpg?v=1785790807","url":"https:\/\/www.truphaeinc.com\/products\/diplomat-cobra-matte-black-guilloche-rollerball-pen","provider":"Truphae","version":"1.0","type":"link"}
