The pen is pictured with an optional purple lacquered nib, which is a wonderful complement to the overall look.This is an averaged sized pen, not too big and not too small. Definitely an eye-catcher. The pen can be made with a clip or roll stop. ","images":["https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174619.jpg?v=1581279787","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174629.jpg?v=1581279787","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174656.jpg?v=1581279787","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174800.jpg?v=1581279787","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174838.jpg?v=1581279787","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174848.jpg?v=1581279787","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/20180419_174710.jpg?v=1581279787"],"price":199.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.673Z"},"share_url":"https://firestarter.network/l/lst_G7zY_8W_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
