The Pilot Tank eye dropper fountain pens are very traditional and has been in the market for more than 40 years. The unique plastic cup like design at the nib section prevents ink from leaking and you really don't need O rings and silicone gel. The steel nib is very smooth and easy to use. The fountain pen will come with a plastic pipette to facilitate the ink filling.
Filling System This pen was intended to be used as an eye dropper, and comes fitted with a little plastic insert that improves the pen's performance as an eye dropper. It helps create a good seal and acts as an O-ring.
If the insert is removed, the pen will accept Pilot ink cartridges or converters. (It takes a bit of tugging to get the plastic insert out, and you also need to remove a small sponge that is installed in the end of thje barrel. Any tool with a little hook on the end can be used to pull it out.)
