{"type":"firestarter.listing","listing":{"id":"lst_OLDdJK0M","product_name":"Sprout","category":"Magnetic","description":"Sprout is a leafy green nail polish with super fine silver-white magnetic pigment and a light green shimmer. Use our magnetic tools while the polish is wet to activate the magnetic particles, creating captivating 3D nail art designs. Magnetic wand and Lucky Horseshoe Magnet sold separately.\nSprout is fresh air in nail polish form. It’s that clean, botanical green that makes you want to touch grass and also look expensive while doing it. The fine magnetic pigment gives a smoother, glassier magnetic effect that shifts beautifully as you move. Cat-eye it for a crisp streak of light, or velvet it for a soft, frosted glow that looks like spring sunlight filtered through leaves.","images":["https://cdn.shopify.com/s/files/1/0622/7797/6235/files/product-sprout-rectlowres.jpg?v=1773847080","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/swatch-sproutgaby-rectlowres_34637922-9508-4c63-b01e-7212257ac9d6.jpg?v=1773847080","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/swatch-sprouthannah-rectlowres_1ade063b-ae79-4eb4-9297-01ba75bbb721.jpg?v=1773944138","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/swatch-sproutlola-rectlowres.jpg?v=1773944138","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/texture-sprout02-rectlowres.jpg?v=1773943208","https://cdn.shopify.com/s/files/1/0622/7797/6235/files/texture-sprout01-rectlowres.jpg?v=1773943208"],"price":15.5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:18.615Z"},"share_url":"https://firestarter.network/l/lst_OLDdJK0M","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
