There are no monsters in this bottle, but plenty of inky goodness to keep you writing for longer.\n\nTransform the way you create with an ink colour that sets you apart!\n\nMost pens offer ink cartridges in a limited selection of colours. I want to change that by bringing you this range of beautifully rich and distinctive inks – with no need to dispose of or replace an empty cartridge.\n","images":["https://cdn.shopify.com/s/files/1/0089/6129/4417/files/mini-fountain-pen-ink-loch-ness-packaging-bottle.jpg?v=1739535818","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/mini-fountain-pen-ink-strawberry-jam-pipette.jpg?v=1761596247","https://cdn.shopify.com/s/files/1/0089/6129/4417/files/mini-fountain-pen-ink-packaging.jpg?v=1761596247"],"price":7.5,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.376Z"},"share_url":"https://firestarter.network/l/lst_p8kQnVkp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
