Description This vintage Esterbrook Renew Point replacement nib and feed unit is marked 9968, a Firm Broad nib made of stainless steel. Esterbrook Renew Point nib units are interchangeable, and to change them, you simply unscrew one and screw in another one. As these are New Old Stock just like they left the factory 80 years ago, there may be some carboard dust in the nib and feed and it is recommended to flush the nib with water prior to first use. Please share with your fellow pen collectors and limit yourself to one nib per person per size. Please note: Imprint may vary slightly from picture.
