{"type":"firestarter.listing","listing":{"id":"lst_cO8_yFXi","product_name":"Lamy 2000 Fountain Pen","category":null,"description":"The classic Bauhaus design, exquisitely made in Germany. Known as the 'cigar pen' thanks to its shape, this is the one and only fountain pen we stock at Mark+Fold. \nDesigned and first produced in 1966, this is a timeless classic and still one of the most modern writing instruments today. It is a family favourite and one that we have owned ourselves for many years. It writes beautifully and all the details are just right.\nThis is a pen for life and very sustainable, as it is refilled from an ink pot via a piston mechanism — no cartridges or refills.\nDetails\nPiston-operated filling system with fiberglass, stainless steel and matt brushed finish. Platinum coated 14 ct. gold nib.\nWe hold the Medium nib in stock, but can also provide Fine, Extra Fine, Broad, Extra Broad, Oblique and Left-handed.\n ","images":["https://cdn.shopify.com/s/files/1/0435/6698/9476/files/Mark_Fold_Lamy-2000-fountain-pen-1.jpg?v=1755878514","https://cdn.shopify.com/s/files/1/0435/6698/9476/files/Mark_Fold_Lamy-2000-fountain-pen-2.jpg?v=1755878514","https://cdn.shopify.com/s/files/1/0435/6698/9476/products/Lamy-2000_1.jpg?v=1774788691","https://cdn.shopify.com/s/files/1/0435/6698/9476/files/Screenshot_2025-06-19_at_13.53.10.png?v=1774788691","https://cdn.shopify.com/s/files/1/0435/6698/9476/products/DIA-2021_scene_2_747eed48-8945-44a3-9889-0a63eef1232c.jpg?v=1774788691"],"price":260,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:16.456Z"},"share_url":"https://firestarter.network/l/lst_cO8_yFXi","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
