My Eyedropper Kits consist of a simple plastic pipette and a small pot of silicone grease. Here is a brief instruction on how to fill your eyedropper pen:
Remove cap, unscrew point section, and, bt the use of an eyedropper, fill the barrel to just below the bottom of the internal threads with ink. Dry the end of the barrel and threads, if moist, and apply a little silicone grease to the threads. Then screw the two parts firmly together thus ensuring a tight, dry joint. If the feed has been allowed to dry out through non-use, the ink will flow correctly as soon as the fissures become moist. Alternatively, you can dip the nib in a bottle of ink to help draw from the reservoir.
