{"type":"firestarter.listing","listing":{"id":"lst_kW9TdSxB","product_name":"CASTILLO HEADBAND","category":"Headbands & Crowns","description":"Airy, architectural, and impossibly lightweight. The Castillo Headband features slender gold bands that arc gently across the crown like a modern-day tiara.

Distinct enough for everything else.\nAvailable in 14K Gold and Silver Plating.\nMade in NYC.\n ","images":["https://cdn.shopify.com/s/files/1/0359/1392/4746/files/CastilloHeadband.jpg?v=1749247505","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/IMG_9763.jpg?v=1756341019","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/IMG_9791.jpg?v=1756341069","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/IMG_9772copy.jpg?v=1756341066","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/5E233D0A-302E-493C-B81E-B93F376EB5A6.jpg?v=1756341101","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/0C0E6C14-F66E-4533-AFC7-D54D141C8F98.jpg?v=1756341056","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/0395F6ED-05FE-44AF-BDEA-4A294D96A04E.jpg?v=1756341066","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/IMG_0641.jpg?v=1756341036","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/IMG_0630_94ded6e4-e2f6-444a-832e-264e664c387e.jpg?v=1756341078","https://cdn.shopify.com/s/files/1/0359/1392/4746/files/CastilloHeadbandSilver.jpg?v=1756337202"],"price":198,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:02.319Z"},"share_url":"https://firestarter.network/l/lst_kW9TdSxB","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
