Description Presenting the Esterbrook Estie! The Esterbrook name has been tied to writing and pens for over a century, and the Estie is the newest evolution of the vision from the Esterbrook name. The Esterbrook Estie ballpoint in Tortoise with Gold trim is made of gorgeous brown marbled acrylic resin with a gold-plated solid Palladium clip. The clip has been specially engineered to easily slide in or out of a shirt pocket without assistance while still maintaining a firm grip. The Estie ballpoint has a smooth twist mechanism that extends and retracts the ballpoint refill. The Esterbrook Estie ballpoint uses the Parker Style ballpoint refill. Please note that items in the Outlet are a final sale.
