{"type":"firestarter.listing","listing":{"id":"lst_wGlde8Ag","product_name":"Martexin Original Wax","category":"Accessories","description":"Martexin® Original Wax. The waxed canvas used in WaterField products is coated with Martexin Original Wax, resulting in a rugged, distressed look. It's a highly specialized textile that precludes normal cleaning. Water repels, and stains can be wiped off with a damp cloth.\n\nYou can touch-up or refresh the wax on your canvas with a tin of Martexin Original Wax. This special formula can be applied with ease by using minimal heat. This 1.5 oz. (42g) size is enough to treat large-sized bags.   ","images":["https://cdn.shopify.com/s/files/1/0281/2796/products/Wax.jpg?v=1614974960"],"price":8,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:54.461Z"},"share_url":"https://firestarter.network/l/lst_wGlde8Ag","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
