{"type":"firestarter.listing","listing":{"id":"lst_eQNeeOW9","product_name":"Zoom Fountain Pen Nib","category":"Fountain pens","description":"Zoom by name, zoom by nature. This nib will quickly become your absolute favourite! For anyone who dares to call fountain pens 'boring' or 'old hat,' the Zoom nib is here to prove them wrong. It finds an empty phone box, whips off its glasses, dons a cape, and zooms straight onto desks to save the day.\nDesigned for those who love to switch things up, this nib gives you the freedom to vary your line width simply by adjusting the angle of your pen to the page. From fine to double broad, and even extra-fine when reversed, it’s like having a whole toolbox of nibs in one.\nAt a natural angle, the Zoom nib writes as a medium-broad and glides across the page with incredible smoothness. It’s wonderfully forgiving, so whether you’re rocking, rolling, or tilting your pen, it still lays down a consistent, beautiful line.\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.\nPerfect for expressive journaling, bold lettering, or experimenting with new techniques, the Zoom nib is made for curious writers who love to explore.\nAnd yes, it’s a bit of an investment – but here’s why. Each Zoom nib is painstakingly hand-ground into its signature shape, a time-intensive process that ensures every single tip is perfectly crafted for your writing adventures. Quality like this takes time, but trust us – it’s worth it.","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/zoom-fountain-pen-nib.jpg?v=1737634482","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/zoom-fountain-pen-nib-studio-pen.jpg?v=1738068987","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/fude-and-zoom-fountain-pen-nibs_f6414631-8c30-47a6-90c5-a09b7ae8075f.jpg?v=1738069052","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/fude-and-zoom-fountain-pen-nibs2_bd826730-7960-4092-92b4-6f471a38f6c3.jpg?v=1738069026"],"price":45,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.074Z"},"share_url":"https://firestarter.network/l/lst_eQNeeOW9","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
