{"type":"firestarter.listing","listing":{"id":"lst_nlFmQ7Tb","product_name":"Cryospring - XL Ice Block Mold","category":"Cold Therapy","description":"\n\n7 lb solid ice blocks for extended cold retention: Large solid blocks have dramatically less surface area per pound than cubed or crushed ice — melt significantly more slowly for fewer refills and longer cold water temperature maintenance without a chiller.\n\nBPA-free silicone construction: Food-safe, inert material with no known leaching concerns — appropriate for water that goes directly into a cold plunge. Silicone also releases frozen blocks more easily than plastic molds.\n\nSteel-reinforced rim: Maintains the mold's structural integrity when carrying a full 7 lb frozen block — prevents the rim from deforming under the weight during transport from freezer to tub.\n\nDishwasher safe: Clean thoroughly between uses without concern for material degradation from heat or detergent.\nFree shipping to the lower 48 states.\n","images":["https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IceBlock_web_03.jpg?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IceBlock_web_04_1.jpg?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IceBlock_web_02.jpg?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IceBlock_web_01.jpg?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IceBlock_web_three.jpg?v=1780604351","https://cdn.shopify.com/s/files/1/0508/3670/1334/files/IceBlock_web_five.jpg?v=1780604351"],"price":19,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:55.645Z"},"share_url":"https://firestarter.network/l/lst_nlFmQ7Tb","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
