{"product_id":"platinum-cf-3000-brush-pen","title":"Platinum CF-3000 Brush Pen","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Platinum CF-3000 is a refillable brush pen built around a polyester ultra-fine fibre tip — a synthetic bristle that delivers the expressive line variation of a traditional brush with the consistent ink control of a pen. The tip is responsive to pressure and angle, tapering to hairline strokes at the lightest touch and opening up to bold, fluid marks when pressed more firmly. It is a tool that rewards deliberate use — well suited to calligraphy, lettering, illustration, and expressive mark-making.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe body is made from aluminium with a slim, clean profile and a push-on cap that also posts securely to the back for a balanced writing length. The cap's compression fit keeps the tip sealed and the ink from drying, which is important given the carbon pigment ink the pen ships with. That ink — Platinum's SPF-200 water-based pigment carbon ink — dries to a rich, permanent black that is water-resistant once dried and will not fade with heat or light exposure. It is the same archival-quality pigment ink used across Platinum's brush and fountain pen range.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe tip is replaceable and sold separately, and the pen takes Platinum's proprietary cartridges or a Platinum converter for use with bottled ink. One ink cartridge is included.\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\"\u003ePolyester ultra-fine fibre brush tip — pressure-sensitive for expressive line variation\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSlim, lightweight aluminium body with push-on\/post cap\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eIncludes one Platinum SPF-200 water-based pigment carbon ink cartridge\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWater-resistant and fade-resistant once dried — suitable for archival and layering work\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCompatible with Platinum proprietary cartridges and Platinum converter (sold separately)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eReplaceable brush tip available separately\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLength capped: 13.5 cm | Diameter: 1.1 cm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMade in Japan\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pentel","offers":[{"title":"Default Title","offer_id":43163169128515,"sku":"PL-CF3000","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2976\/4338\/files\/PlatinumCF3000_1.jpg?v=1776620549","url":"https:\/\/shopnoteworthy.com\/products\/platinum-cf-3000-brush-pen","provider":"Noteworthy Stationery","version":"1.0","type":"link"}
