{"type":"firestarter.listing","listing":{"id":"lst_OBiDTNzV","product_name":"Fude Fountain Pen Nib","category":"Fountain pens","description":"Looking for the ultimate inky goodness? This is the nib for you! Fude means \"brush\" in Japanese, and it’s an absolute ink monster, effortlessly laying down expressive strokes without hesitation. With its distinctive bent tip set at a 45-degree angle, the Fude nib allows you to control line width simply by adjusting the angle of the pen to the page – perfect for creating everything from bold, sweeping strokes to delicate, fine lines.\nDon't expect a traditional fountain pen nib experience here, this nib is perfect for those who prize experimentation over perfectionism. It's the ideal nib for lettering enthusiasts, illustrators, or anyone looking to explore their artistic side, the Fude nib transforms ordinary pen strokes into something extraordinary.\nMade exclusively for our fountain pens, all nibs are tipped with hard-wearing iridium for effortlessly smooth writing. You can choose between uncoated stainless steel (a sleek silver finish) or 14k gold plating (a classic gold finish) – the difference is purely aesthetic, so both options offer the same exceptional performance. Plus, every nib is interchangeable, allowing you to effortlessly switch styles whenever inspiration strikes.\nWhether you're sketching, journaling, or signing your name with a flourish, the Fude nib is your go-to for endless creative possibilities.","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/fude-fountain-pen-nib.jpg?v=1737634482","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/fude-fountain-pen-nib-studio-pen.jpg?v=1738069094","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/fude-and-zoom-fountain-pen-nibs.jpg?v=1738069075","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/fude-and-zoom-fountain-pen-nibs2.jpg?v=1738069064"],"price":26,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.072Z"},"share_url":"https://firestarter.network/l/lst_OBiDTNzV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
