{"type":"firestarter.listing","listing":{"id":"lst_zbxP4I_W","product_name":"Black Widow","category":"Shimmer","description":"Black Widow is a sultry black nail polish with a seductive red shimmer and delicate holographic sparkle. Our shimmer polishes are packed with glimmering pigments which give them a unique multidimensional finish, unlike any other.\nDark, dangerous, and impossible to ignore. Black Widow is the kind of black that feels alive, catching flashes of red beneath the surface like a warning sign you choose to ignore anyway. It’s sleek, commanding, and unapologetically bold. The polish you reach for when you are fully in control and not asking for permission.","images":["https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-product-blackwidow01.jpg?v=1766520279","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-gaby-blackwidow01.jpg?v=1766521730","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-hannah-blackwidow01.jpg?v=1766521730","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-lola-blackwidow01.jpg?v=1766521730","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/macrotextureshot-blackwidow01-corrected.jpg?v=1767209105"],"price":14.5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:18.709Z"},"share_url":"https://firestarter.network/l/lst_zbxP4I_W","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
