{"type":"firestarter.listing","listing":{"id":"lst_p35CywRN","product_name":"The Studio Pocket Fountain Pen 2.0","category":"Fountain pens","description":"Finally, a fountain pen that’s as interesting as you are.\nGone are the days of fountain pens that feel like they’ve been mass produced in some Dickensian, utilitarian workshop. The Studio Pocket Fountain Pen 2.0 is hand-assembled right here in our studio, with 49 possible colour combinations – plus the option to laser engrave it, making it feel as unique to you as your handwriting.\nDespite its diminutive 90mm size when capped, it extends to a comfortable 130mm when posted – making it (dare we say it?) the most portable and comfortable fountain pen in the world. We might be blowing our own trumpet here, but we’ll let you be the judge.\nAnd nibs – oh, wonderful nibs. Often under appreciated, but never overlooked by us. The Studio Pocket Pen is a bit like the Go-Go Gadget of the fountain pen world: with three interchangeable nibs to choose from and six more creative nibs you can add, you can switch things up depending on your mood, your writing style, or your next creative adventure.\nThis refresh is all about making the fountain pen experience feel more personal, more joyful, and a whole lot more fun. Because when your tools reflect who you are, creativity flows that little bit more freely.\n","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/PocketPen_FreeMiniInk_SQ1.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-mix-and-match-on-ink.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-mix-and-match-desk.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-ink.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-mix-and-match.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-mix-and-match-nib-annotation.png?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-size-comparison.gif?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-mix-and-match2.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/studio-pocket-fountain-pen-refill.jpg?v=1753889619","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/pocket-fountain-pen-all-colour-annotated-no-black.jpg?v=1753889619"],"price":85,"currency":"USD","in_stock":true,"inventory_qty":2499750,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.009Z"},"share_url":"https://firestarter.network/l/lst_p35CywRN","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
