{"type":"firestarter.listing","listing":{"id":"lst_0RP1oZOX","product_name":"Treble Maker","category":"Thermal","description":"Treble Maker is a thermal nail polish that changes color based on temperature. This polish changes to a deep black when cold and to an amethyst purple when warm. You may notice shades of dusky purple as the polish travels through the color spectrum between the cold and warm states.\nPlayful with a dark streak, this polish shifts with the heat of the moment. It’s the mischief in the orchestra pit, the note that makes you lean in closer.\nPlease note that thermal polishes dry to a matte finish. We recommend applying top coat for a glossy shine. Store product in a cool, dark place.","images":["https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-product-treblemaker01.jpg?v=1761861676","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-lola-treblemakertransitionstate01.jpg?v=1761861720","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-macro-treblemaker01_8691bd2a-0712-4f31-a158-ee12b2b67ba7.jpg?v=1762210876","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-lola-treblemakercoldstate01.jpg?v=1762210876","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-lola-treblemakerwarmstate01.jpg?v=1762210876","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-hannah-treblemakertransitionstate01.jpg?v=1762210876","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-hannah-treblemakercoldstate01.jpg?v=1762210876","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/LowRes-swatch-hannah-treblemakerwarmstate01.jpg?v=1762210876"],"price":16.5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:18.741Z"},"share_url":"https://firestarter.network/l/lst_0RP1oZOX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
