Cheap Joe's Sketchmaker Eyedropper Pen Conversion Kit
Turn your fountain pen barrel into a huge reservoir for your favorite fountain pen inks with Cheap Joe's Sketchmaker Eyedropper Pen Conversion Kit. It's easy! Simply unscrew the pen barrel and remove the cartridge or converter. Stretch the O-ring over the threads of the grip down to the base (the grip is the part with the fountain pen nib attached). Spread a dab of silicone grease on the threads of the grip using your finger or a Q-Tip. Screw the barrel on and off a couple of times to make sure the grease creates a leak-proof seal. Use the syringe to transfer your favorite fountain pen ink from the bottle to the barrel. Screw the barrel back on and hold the pen vertically until the feed is saturated. Enjoy longer writing and drawing times with your fountain pen!
Eyedropper Pen Conversion Kit - Includes two 3 ml. syringes, 4 O-rings, and a jar of silicone grease.
Note - This technique works on pen barrels that will not have any metal coming into contact with the ink, as metals can react with fountain pen ink resulting in corrosion of the barrel.
