This pen is furnished with an 18k Gold, two-toned #6 nib. What has been described by many Danitrio collectors as the fireball nib is an image of “Kaen-Kohai” which is a flame-shaped halo of “Fudo Myoo” (Acala, the God of Fire). This halo is commonly painted on the back of Japanese Buddhist statues.
