{"type":"firestarter.listing","listing":{"id":"lst_q3ry-mDX","product_name":"Jade Inferno","category":"Ink Bottle","description":"Jade Inferno is a radiant teal that smolders with hints of merlot sheen* in saturation for a subtly molten finish.\n*While it's possible to find sheen in the Jade Inferno when saturated on slightly hydrophobic papers like Tomoe River or Rhodia, this property may require a wet pen and broad nib to achieve in writing. \nPart of the Keystone Formula fountain pen ink line, Jade Inferno is built with traditional dye-colorants. Our ink color swatch is produced with a cotton swab on Tomoe River paper. \nThe 50mL volume will provide approximately 62 standard converter refills assuming a 0.8mL draw. Glass bottles arrive prepared in our beautifully foiled Birmingham Pen Co. gift box.","images":["https://cdn.shopify.com/s/files/1/1237/1088/files/Jade_Inferno_50.jpg?v=1756229680","https://cdn.shopify.com/s/files/1/1237/1088/products/JadeInfernoWritingTestTomoeRiver68gsm.jpg?v=1756323113","https://cdn.shopify.com/s/files/1/1237/1088/files/InkBottleBox60mL_daf977e0-adc8-4e0b-ac15-6c4a492f9072.jpg?v=1756323113"],"price":17,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:18.712Z"},"share_url":"https://firestarter.network/l/lst_q3ry-mDX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
