{"type":"firestarter.listing","listing":{"id":"lst_mEthS9ha","product_name":"Lumos Stainless Steel","category":"Lumos","description":"A special edition, precision-engineered Lumos in stainless steel.\nI’ve crafted approximately 4,000 pens by hand on my marvellous 1960s Myford Super 7 engineering lathe, and the phrase \"they don’t make 'em like they used to\" certainly rings true for this special bit of machinery.\nAbout the Lumos Stainless Steel\nThe stainless steel Lumos embodies the same philosophy of creating something to last a lifetime. It pays homage to time-honoured techniques and machinery with its unique diagonally knurled cap, smooth and precise body finish, incredibly hard-to-machine triple start threads (which mean the cap unscrews three times as fast), and, of course, being made from the most enduring of materials, stainless steel.\nI’m sure my Lumos and lathe will be hanging out together for generations to come, reminiscing about the good old days.\nNote: As it is made from stainless steel, you’ll notice that this special edition Lumos has a reassuring weight in the hand – a feature many of our customers love. Please be aware that this pen weighs more than it's standard Lumos counterparts, offering a unique and satisfying writing experience.\n\n","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/stainlesssteelLumosonplinth.jpg?v=1745323387","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_SS.jpg?v=1761211292","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/stainlesssteelLumoslid.jpg?v=1761211292","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/StainlessLumoswithShopDrawing.jpg?v=1774348191","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/StainlessLumoswithpersonalisationoptions.jpg?v=1761211292","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-stainles-steel-annotated.jpg?v=1761211292","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/Fountain_Ink_GRP_SQ.jpg?v=1761212367","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-pro-duo-stainless-steel.jpg?v=1772122699","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_SSDuo.jpg?v=1761218201","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/Lumos_Creative_Tip_Set_LS_SQ.png?v=1774603901","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-pro-single-stainless-steel.jpg?v=1774348191","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_SSSingle.jpg?v=1761218201","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-full-creative-tip-set-and-mini-ink.jpg?v=1774603901","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-mini-stainless-steel.jpg?v=1761218201","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/LumosMetals_WEB_SSMini.jpg?v=1761218201","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/lumos-reservoir-refill.png?v=1774603901"],"price":152,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.052Z"},"share_url":"https://firestarter.network/l/lst_mEthS9ha","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
