By fusing the traditional mechanisms of the fountain pen with a modern industrial design, we have created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present. The Diamond 580 comes with a benchmark ink-filling mechanism and has all detachable parts. We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cspan\u003eAccessories with \u003ca href=\"https:\/\/thepapermind.mom\/products\/twsbi-diamond-580-fountain-pen-replacement-nib-set\"\u003espare 580 nibs\u003c\/a\u003e and a \u003ca href=\"https:\/\/thepapermind.mom\/products\/twsbi-diamond-50-ink-bottle-50-ml-polished-aluminum\"\u003ematching inkwell\u003c\/a\u003e specially designed for the Diamond 580.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy It's Special\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFully transparent throughout — the clear grip section lets you watch ink move through the feed\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFaceted \"diamond-cut\" barrel that refracts light through the ink and keeps the pen from rolling\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHigh ink capacity, roughly 1.95 ml via piston filler\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eChrome-plated trim and spring-metal clip\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFully user-serviceable; ships with a wrench and silicone grease for disassembly and maintenance\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGerman-made stainless steel nib\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eType: Fountain pen, fine nib\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMaterial: Clear acrylic body and section\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTrim: Chrome-plated\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFilling: Piston\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInk capacity: ~1.95 ml\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCap: Screw closure (posting not recommended — the cap engages the piston when twisted on the back)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eClip: Spring metal\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCapped length: 142.2 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBody length: 130 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBody diameter: 13.2 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGrip diameter: 10.2 mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight: ~28 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease note: TWSBI products are not eligible for discounts.\u003c\/em\u003e\u003c\/p\u003e","brand":"TWSBI","offers":[{"title":"Broad","offer_id":47860025819301,"sku":"TSB-7443140","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/6046\/2501\/files\/TWSBI_Diamond_580_Fountain_Pen_-_Clear_-_Piston_Filler_-_Demonstrator_-_Made_in_Taiwan.jpg?v=1779925772","url":"https:\/\/thepapermind.mom\/products\/twsbi-diamond-580-fountain-pen-clear","provider":"The Paper Mind","version":"1.0","type":"link"}
