{"type":"firestarter.listing","listing":{"id":"lst_egNJO8Nx","product_name":"Square Copper Rain Chain","category":"Rain Chain","description":"A simple and beautiful alternative to the downspout, this copper square cup rain chain guides rainfall in a steady cascade from gutter to ground. Unfinished and entirely natural, the copper will weather and patina over time, deepening to a rich verdigris that only improves with age and exposure. Built without welding, each cup is held together with heavy-duty hardware and thick wire for a construction that is as robust as it is elegant, rated for all rainfall conditions.","images":["https://cdn.shopify.com/s/files/1/0720/5824/1345/files/RainChainsLLC_SquareCopperRainChain_3121MCOP_7214.jpg?v=1780412596","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/square-1.jpg?v=1780481849","https://cdn.shopify.com/s/files/1/0720/5824/1345/files/RainChainsLLC_SquareCopperRainChain_3121MCOP_diagram.jpg?v=1780412601"],"price":258,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:19.142Z"},"share_url":"https://firestarter.network/l/lst_egNJO8Nx","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
