Parson's Essential Nib Unit.
Note: It is not a good idea to buy spare nib units for the Parson's or Churchman's. Nibs need to be inside a cap to be kept ready for use or they will dry out and ink deposits accumulate on the 'feed' . This means that the nib unit must be cleaned before it is stored away for later use. It makes more sense to buy additional complete pens.
Note: The Nib and Feed option for the Parson's Essential and Viper's Strike requires an existing nib unit, buy the complete nib unit if unsure.
