ebonite feeder for 2nd gen titanium nib has been developed.
research notes:
1) dual micro slit ink channel applied
2) frontal micro side combs added
3) high accuracy tail section added (no o-ring needed to seal)
4) superb ink flow, while having good resistance against leak in gravitational direction (90 degrees).
5) full utilization of space for comb grooves @ end area
6) the most intricate ebonite feeder developed by eureka
7) a total of 90 prototypes developed, each with different internal designs.
the best design was selected as the final production model.
