{"type":"firestarter.listing","listing":{"id":"lst_DHSzAIXG","product_name":"The Zeitgeist","category":"Fountain Pen","description":"Zeitgeist is a German word that literally translates to \"Time Spirit\". It's meaning or intended translation is \"Spirit of the Age\" or \"Spirit of the times\". Wikipedia has an excellent article on the topic:  https://en.wikipedia.org/wiki/ZeitgeistTrue to its name, I designed this pen to represent our current culture. Sleek lines, bold accents, and stunning color are true to our modern styles and ideals. The pen is dressed with a stainless steel clip and nickel band on the cap. Overall length is a little shy of 6\" capped. Body threads are 13mm and it has a diameter of about .600\" at the body's widest. It gently tapers to the finial allowing the cap to be posted.As shown, the pearlescent teal is the first to grab your attention., then bold swirls of antique silver inspire a feeling of nostalgia and gives it a retro appearance. Made from an incredibly strong and durable epoxy, it will resist scratches and will survive falls and a bit of clumsiness (trust me, my klutz self has tested it thoroughly). There is a wide variety of nib offerings.The pen will come in the teal and antique silver as shown. It will also available in a cobalt steel blue and antique silver (pictures coming soon of this color combo).Buy one today and get with the spirit of the times !","images":["https://cdn.shopify.com/s/files/1/0329/5117/3260/products/TL441.jpg?v=1581279580","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/TL454_20-_20Copy.jpg?v=1581279580","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/TL455.jpg?v=1581279580","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/TL491_20-_20Copy.jpg?v=1581279580","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/TL493.jpg?v=1581279580","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/TL518_20-_20Copy.jpg?v=1581279580"],"price":249.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.705Z"},"share_url":"https://firestarter.network/l/lst_DHSzAIXG","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
