I’ve always believed that the tools we use should bring us joy and reflect the quality of the work we create. It’s why I made the very first calligraphy pen for my wife Gemma all those years ago!\nIt’s an ethos I’ve held close as I’ve embarked on my mission to eliminate single-use pens, which led me to developing The Lumos - an elegant and infinitely refillable alternative to the fineliner. The Lumos has been a huge hit and I’ve been humbled by the fantastic feedback. That’s what inspired me to design this special edition, precision engineered, Lumos Brass.\nAbout the Lumos Brass\nThe first step to making a standout pen is choosing the right material. For me, brass was the winner; it gives the pen a satisfying weight in the hand, and an impeccably shiny and smooth feel.\nI drew inspiration from classic British design from cars to old transistor radios; their heritage and intangible soulful quality influenced the design and the smallest of details. Such as the beautiful finely knurled cap as well as the way in which the pen effortlessly closes with just the right amount of feedback in the hand.\nMeeting these exacting standards requires the ultimate in manufacturing tools and processes. Luckily there’s an expert team based just 20 minutes from my Studio, who use precision lathes that are no stranger to making the finest parts such as watch mechanisms and aerospace components.\nWhether you’re looking for a tool to mirror the beauty of your creative practice, elevate your everyday work, or as a gift for an extra special occasion, I hope you find your perfect pen in the Lumos Brass.\n\n","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-refillable-pen-duo-brass.jpg?v=1761212395","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_Brass.jpg?v=1761212395","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-refillable-pen-brass-lid-2_9f4253aa-9554-41d8-9af5-629810492f36.jpg?v=1774348191","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-refillable-pen-brass-engraving_f72d9eba-2175-44e9-8822-0f0c0e2c2e4a.png?v=1761211184","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/Lumos_Creative_Tip_Set_LS_SQ_5dfa3820-8d95-4b3c-a161-21bbec1ba2c7.png?v=1761211184","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-compatible-inks_f7fba158-2c9c-4e69-9f41-10b53e6bf11c.jpg?v=1761211184","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-full-creative-tip-set-and-mini-ink_4c062bcd-c509-4e88-85cb-853591cbb862.jpg?v=1761211184","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-reservoir-refill_39df13ed-1200-4a5b-967a-2b39e2473516.png?v=1761211184","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_BronzeSingle.jpg?v=1774348191","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_BronzeMini.jpg?v=1761218129","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_BronzeDuo.jpg?v=1772122699"],"price":120,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.522Z"},"share_url":"https://firestarter.network/l/lst_OJ3-Gnzr","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
