Profit Jr. +10 ゆらめく 寒暁（KANGYOU）

A 10ml mini bottle of "flickering ink" that changes color over time and depending on the paper used, along with a fountain pen and converter that express that color.

The fountain pen features resin with iridescent pearl that expresses the shimmering colors of ink. The color changes depending on the angle of view and the way light hits it, revealing and concealing specific colors.

The pen tip is a special "calligraphy pen tip" that allows for both thick and thin writing. The thickness of the line changes with the angle of writing, allowing for variations in strength, enabling you to write lines similar to calligraphy. You can enjoy the changing colors of the shimmering ink even more.
(※ Same pen tip as the 40-degree Fude DE Mannen)
