Description This Edison #6 Jowo single-tone gold Steel Fine nib unit is a complete all-in-one nib and feed unit which screws into your Edison fountain pens that use a #6 JoWo nib unit. This Edison gold-plated steel nib unit generally looks best in pens with gold trim. Please note: Edison is undergoing a rolling change in their gold plated and regular 18kt gold nibs - Two-tone nibs are being phased out in favor of Single-tone gold plated or single-tone 18kt gold. Some nibs are only available in single-tone gold, and the Two-Tone option is no longer available. If this is a concern, please email or call for more details. Additional Edison fountain pen nib units are available separately as well. Make sure to remove the cartridge or converter in the barrel before unscrewing and replacing the nib unit. Please Note: Some 18kt nibs are special order and will take an additional 7-10 days for delivery. We offer Free Shipping on all orders over $59 for US customers, and for orders over $250 for our Canadian customers.
