{"type":"firestarter.listing","listing":{"id":"lst_3pQNOIf8","product_name":"Cervellee","category":"Derbies","description":"It's the minimal Derby for the man who pursues a sober style. This look is casual: wear it either in your spare time or to work, if your office allows you to be more creative, with a black suit. With their full-grain leather and Italian made Vibram rubber sole, it’s the dark brown shoe to perfectly match a pair of structured dark blue jeans, as well as chinos.","images":["https://cdn.shopify.com/s/files/1/1627/0215/files/01_cervellee_tdm.jpg?v=1757336601","https://cdn.shopify.com/s/files/1/1627/0215/files/02_cervellee_tdm.jpg?v=1757336601","https://cdn.shopify.com/s/files/1/1627/0215/files/03_cervellee_tdm.jpg?v=1757336602","https://cdn.shopify.com/s/files/1/1627/0215/files/04_cervellee_tdm.jpg?v=1757336602","https://cdn.shopify.com/s/files/1/1627/0215/files/05_cervellee_tdm.jpg?v=1757336603","https://cdn.shopify.com/s/files/1/1627/0215/files/06_cervellee_tdm.jpg?v=1757336602","https://cdn.shopify.com/s/files/1/1627/0215/files/07_cervellee_tdm.jpg?v=1757336601","https://cdn.shopify.com/s/files/1/1627/0215/files/08_cervellee_tdm.jpg?v=1757336601","https://cdn.shopify.com/s/files/1/1627/0215/files/ZX_cervellee_tdm.jpg?v=1757336602","https://cdn.shopify.com/s/files/1/1627/0215/files/ZZ_cervellee_tdm.jpg?v=1757336602"],"price":530,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:22.339Z"},"share_url":"https://firestarter.network/l/lst_3pQNOIf8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
