This special adaptor was engineered to allow new and modern day Esterbrooks to accept vintage nibs from their back catalogue over 300 different styles. The adaptor, which is also a replacement grip section, has been contoured in a similar shape to vintage Esterbrook grips of the early 50s and 60s, and provides a comfortable grip and feel.
Inside the adaptor is where the real engineering begins! The section has been threaded to accept the majority of Esterbrook nibs and feeds, and is engineered to allow seamless ink flow from the cartridge or converter to the nib.
The adaptor works with the Estie and Estie Oversize pens.
