{"type":"firestarter.listing","listing":{"id":"lst_YCAP-aNf","product_name":"The Madison","category":"Essential Carry","description":"Purpose-built, style-driven.\nThe Madison is the younger sibling of the Mehlville, which was our very first carabiner and continues to be a constant best-seller. Like the Mehlville, the Madison features a machined two-compartment design to keep your keys securely attached—even when getting the Madison on or off a belt loop. The Madison is machined from billet aluminum or titanium, delivering a high strength-to-weight ratio. The thinner design of the Madison means that it always hangs straight; there’s no side-to-side rocking happening here. With less bulk, the Madison is lightweight, functional, and beautiful. Where form and function meet, you’ll find The Madison.\n","images":["https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_25S2_Madison_Grove_PDP_01.jpg?v=1771997288","https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_25S2_Madison_Silver_PDP_01.jpg?v=1771997288","https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_26S1_Madison_Titanium_PDP_01_V2.jpg?v=1771997288","https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_25S2_Madison_GoldBlack_PDP_01_df943651-c678-4c2d-81c1-ac54ace88a43.jpg?v=1771997288","https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_25S2_Madison_Black_PDP_01.jpg?v=1771997288","https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_25S2_Madison_PurpleHaze_PDP_01.jpg?v=1771997288","https://cdn.shopify.com/s/files/1/2272/1733/files/TJB_26S1_Madison_Neon_Buttermilk_Polish_PDP_01_V2.jpg?v=1771874229"],"price":49,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:59.120Z"},"share_url":"https://firestarter.network/l/lst_YCAP-aNf","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
