Description The Pilot Custom 823 fountain pen in Clear is a unique alternative to the everyday user-grade fountain pen. The pump filling system creates a vacuum on the downstroke, filling the barrel about 2/3 full of ink, similar in function to the Sheaffer pens of the 1930's. For best results, follow the instructions on the label on the cap. The clear transparent cap and barrel are accented by a black grip section and end caps, with gold trim, and the 14k nib is extremely smooth and offers a wonderful writing experience. The pen comes with a full bottle of ink in a unique design, in a larger satin-lined presentation box. We offer Free Shipping on all orders over $59 for US customers, and for orders over $250 for our Canadian customers. The Pilot Custom 823 Clear body is new for 2024.
