{"type":"firestarter.listing","listing":{"id":"lst_0llQLxgr","product_name":"The Wren - Refillable Writing Pen (solid colours)","category":"Wren","description":"\nWren - Take Flight & Write\n Writing Instrument of the Year 2025, Stationery Awards, London\nA beautiful and infinitely refillable writing pen, equipped with a Japanese-made writing tip. We're on a mission to make choosing refillable options easier, so you can now buy two (or more!) Wren pens and save 10%\nEach year, an estimated 9 billion pens are thrown away, contributing to growing environmental waste. Many writing tools are designed with convenience in mind, often leading to a cycle of frequent replacements, which generates significant waste and limits options for those seeking more sustainable, long-lasting choices.\nAs a product designer and craftsman who loves writing, I became frustrated with the waste created by disposable pens. They would pile up in drawers, waiting for a specific refill, or worse, end up in the bin despite being perfectly usable – if only they had ink.\nAfter years of designing and handcrafting calligraphy and fountain pens for creatives worldwide, I decided it was time to tackle one of the biggest culprits: the everyday writing pen. The result? The Wren – a pen designed not only to write beautifully but also to last a lifetime, helping to reduce the mountains of waste created by disposable pens.\n\n","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wrensizedifference_w_background_stationery_awards-winner.jpg?v=1772110801","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-blush-lilac.jpg?v=1772110801","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-blush-lilac-ivy-with-ink.jpg?v=1772110801","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-sage-packaging.jpg?v=1772110801","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-all-colours-gif.gif?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-blush-packaging.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/Wren_Tips_LS_SQ.jpg?v=1772110801","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-reservoir-refill.jpg?v=1756238812","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-compatible-inks.jpg?v=1774603901","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-all-colours-detail.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-blush-midnight-eiffel-tower.jpg?v=1756238812","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-all-colours-3.jpg?v=1768907889","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-sage.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-raspberry.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-blush.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-iris.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-ivy_66280ea9-bf76-42a3-9e99-4a721dbdd434.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-lilac.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-midnight.jpg?v=1747389430","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/wren-refillable-writing-pen-black.jpg?v=1747389430"],"price":45,"currency":"USD","in_stock":true,"inventory_qty":79992,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:22.513Z"},"share_url":"https://firestarter.network/l/lst_0llQLxgr","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
