Description This Edison #6 Jowo Steel Fine Flex nib unit in Silver 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 steel nib unit generally looks best in pens with silver trim. The Fine Flex nib has some give or softness to it, but it does not have the "wet noodle" feel of a vintage gold flex nib. Make sure to remove the cartridge or converter in the barrel before unscrewing and replacing the nib unit. Additional Edison fountain pen nib units are available separately as well. 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.
