{"product_id":"montblanc-starwalker-extreme-doue-fountain-pen-medium","title":"Montblanc StarWalker Extreme Doue Fountain Pen Medium","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe StarWalker Extreme, is an interesting entry into the range. The dome up top has gone from Montblanc's usual clear resin to a translucent orange that catches the light like something mid-launch. There's a real sense of energy to it, which feels fitting for a pen with \"Extreme\" in the name. The black precious resin barrel carries the Extreme pattern, pulled from Montblanc's own archive of artwork and shared with their Extreme leather goods, so if you're the type who likes your pen and your wallet having a conversation with each other, this is your moment.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe cap and clip are both finished in ruthenium-coated metal, giving a cool, slightly industrial sheen that plays nicely off the warmth of that orange dome. Even the nib gets the treatment: solid 18k (Au 585) gold, ruthenium-coated, with its own special embossing, so the detailing carries all the way down to the page.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBlack precious resin barrel with Extreme pattern\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRuthenium-coated cap and clip\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eNib: Solid 18k (585) gold, ruthenium-coated, with special embossing\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDimensions: 135.7mm x 14.9mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight: 37.25g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Montblanc","offers":[{"title":"Default Title","offer_id":49266561417459,"sku":"MB00390","price":825.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/6388\/4787\/files\/Untitled-18June2026at06.21.50-1.png?v=1781760299","url":"https:\/\/cultpens.com\/products\/montblanc-starwalker-extreme-doue-fountain-pen-medium","provider":"Cult Pens","version":"1.0","type":"link"}
