Classic Fountain Pen Clear Body

Replace the body of your Classic Fountain Pen with a piston filler transparent body. This lets you fill and empty the pen using a piston device. It also lets you view the contents of your reservoir to see what color ink you are using. Just screw the old barrel off and screw on this clear body. Make sure the o-ring is seated properly. Now fill and empty the pen using the screw piston device. Filling a pen using a piston is the cleanest way to fill and empty your pen. You can unscrew the clear body from the pen to clean the reservoir.
