Sailor Luminous Shadow Storm Blue Fountain Pen (KOP's Nib)

The Luminous Shadow Fountain Pen is a marble-patterned acrylic cutting fountain pen created by mixing multiple colors. There are no two identical patterns, and they show various expressions depending on how they are shaved.
Luminous shadow is a fountain pen that links the concept of "light and shadow" and the uncertain features of the "shape" of the marble pattern. Equipped with a super-large 21-karat gold nib unique to Sailor Pen and a black IP-finished nib.
