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 rollerball in Tortoise with Palladium trim is made of gorgeous brown marbled acrylic resin with a 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 Esterbrook Estie also includes a "Cushion Cap" closure system featuring a spring-loaded inner cap. This not only gives the cap a satisfyingly secure closure, but also prevents the refill from drying between uses! Some colors may ship in 7-10 days.
