{"type":"firestarter.listing","listing":{"id":"lst_Nnp5NrOS","product_name":"SMJ Polishing Cloth","category":null,"description":"Your jewelry deserves to be worn, not stored. This ultra-soft microfiber cloth is embedded with a gentle polishing compound that restores shine to gold fill, sterling silver, and solid gold — no harsh chemicals, no risk of scratching.\nOne thing to know: the cloth will turn black with use. That's normal, and it means it's working. The cloth is still good to go.\nEach cloth is embossed with the SM logo and comes tucked in a paper envelope with a care card. Small, useful, and a little elevated — the kind of thing that's good to have in your drawer.\nAdd it to your order and actually take care of the things you love.","images":["https://cdn.shopify.com/s/files/1/0524/6107/6679/files/JewelryPolishingCloth.png?v=1773776221"],"price":5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:45:33.679Z"},"share_url":"https://firestarter.network/l/lst_Nnp5NrOS","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
