{"product_id":"platinum-ink-cartridges-black-pack-of-2","title":"Platinum Ink Cartridges, Black - Pack of 2","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePlatinum ink cartridges are a clean, fuss-free way to keep your Platinum fountain pen writing. Each cartridge holds approximately 1.0 ml of dye-based ink — an above-average capacity for a fountain pen cartridge — and is built sturdily enough to resist evaporation well between writing sessions. The tapered body features Platinum's distinctive ball-bearing closure, which seats deeper into the pen's feed than most cartridge formats and creates a snug, near-leakproof seal.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTo install, push the ball-bearing end firmly into the pen's section until you feel it click into place and the ink begins to flow. The cartridge will sit deeper than you might expect — this is intentional, and is what gives the format its reliable seal. It works particularly well alongside Platinum's slip-and-seal cap mechanism, helping to keep the pen fresh even after longer gaps between use.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePlease note that Platinum cartridges use a proprietary format and are not compatible with standard international cartridge pens. Each pack contains two cartridges.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFeatures\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=\"whitespace-normal break-words pl-2\"\u003eApproximately 1.0 ml of ink per cartridge — above average for a fountain pen cartridge\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eProprietary Platinum format — compatible with all Platinum fountain pens\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTapered body with ball-bearing closure for a snug, near-leakproof fit\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSturdy construction with good resistance to evaporation\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWorks with Platinum's slip-and-seal cap mechanism\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDye-based ink formula\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e2 cartridges per pack\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\" style=\"font-weight: bold;\"\u003e\u003cstrong\u003eNon Waterproof\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMade in Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/shopnoteworthy.ca\/collections\/inks-refills-1\" title=\"Inks \u0026amp; Refills\"\u003eSee all inks and refills\u003c\/a\u003e\u003c\/p\u003e","brand":"LSF","offers":[{"title":"Default Title","offer_id":43127131177027,"sku":"PL-SPN100A-B","price":4.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2976\/4338\/files\/PlatinumInk_Pack2_Black.jpg?v=1775753376","url":"https:\/\/shopnoteworthy.com\/products\/platinum-ink-cartridges-black-pack-of-2","provider":"Noteworthy Stationery","version":"1.0","type":"link"}
