{"type":"firestarter.listing","listing":{"id":"lst_nnMBDwW-","product_name":"Witching Hour","category":"Thermal","description":"Witching Hour is a thermal nail polish with a scattered holographic effect that changes color based on temperature. This polish changes to black when cold and spiderweb grey when warm.\nSummer’s over and so is happy hour: it’s time for gothic gatherings. Summon your coven, bring out your best cauldron, and enjoy an evening of popping potion bottles. If the neighbors ask what all the shrieking and cackling is about, all they need to know is you’re having a fun night in with your besties – quick, hide the bats.\nPlease note that thermal polishes dry to a matte finish. We recommend applying our Looking Glass Top Coat for a glossy shine. When observing the thermal color shifts please note you may see an array of hues as the polish travels across the color spectrum to the noted color states. Store polish in a cool, dark place.","images":["https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Bottle-WITCHING-HOUR-Low-Res__36667.jpg?v=1670887586","https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Kenya_WITCHINGHOUR_Cold_LOW_RES__57243.jpg?v=1670887588","https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Lauren_WITCHINGHOUR_Transition_LOW_RES_02__67866.jpg?v=1670887589","https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Kenya_WITCHINGHOUR_Warm_LOW_RES__22716.jpg?v=1670887591","https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Kenya_WITCHINGHOUR_Transition_LOW_RES__94443.jpg?v=1670887592","https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Lauren_WITCHINGHOUR_Transition_LOW_RES_01__96757.jpg?v=1670887594","https://cdn.shopify.com/s/files/1/0622/7797/6235/products/Emiline_WITCHINGHOUR_Transition_LOW_RES__08111.jpg?v=1670887596"],"price":16.5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:18.823Z"},"share_url":"https://firestarter.network/l/lst_nnMBDwW-","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
