Osprey Nib unit protector spare
The Osprey nib unit protector is designed to protect your nib and user during handling. Spare replacement plastic guard covers are now available to fit your own dipnibs or nibunits with.
Please note, the nib unit protector is designed to protect your nibs and insert when not being used in your fountain pen. If you are going to be using the nib protector, make sure your stock or Flexpert unit is emptied and flushed first. You should only keep your insert inked if you plan to have it fitted and secured in the fountain pen itself. The nib protector is designed to protect user and nib when it is not in the fountain pen. If you store an insert filled with ink with a nib protector outside of the fountain pen, there are chances that a small amount may drip inside the cap. To prevent your insert from either leaking or drying out, it is advised that one should empty and flush the insert.
The Osprey Nib unit protector is handy when swapping or handling nib units. Imagine being able to safely store and swap your own set of perfectly ground nib units!
