Once the polish is not able to transition anymore the color will remain in either the hot or the cold state.\nWe suggest using a base coat and 2-3 coats of polish followed by a top coat. 10-free. Vegan. Cruelty-free. Nontoxic.\nThis polish comes with a removable handmade decorative bronze cap atop our standard black matte nail polish cap - merging artistry with function. To forego bronze caps on your order, click here.","images":["https://cdn.shopify.com/s/files/1/0063/6692/0773/files/IMG-8272.jpg?v=1698502707","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_ca7bd555-1fa5-44cc-99e3-c00bdc23fe3c.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_7bf71ca5-57d6-46f1-bc4b-67ab1be4e3b5.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_4f4df303-e413-4aeb-80f4-f729ff959e80.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_f7b8c76b-4044-4e88-b693-0d54d185b0a9.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_c22fa8a1-bb8b-45b7-b4f9-4a01556e70ad.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_6383a9d6-3b6b-4100-8d26-2e27fdac753d.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_17035205-d342-41ae-bc2c-16525cb758fd.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/image_25926cbe-661a-40d3-adbb-9e35e7cb6696.jpg?v=1771516754","https://cdn.shopify.com/s/files/1/0063/6692/0773/files/GUTSY_0250.jpg?v=1771516754"],"price":16,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:20.240Z"},"share_url":"https://firestarter.network/l/lst_F-NOZv6D","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
