NAGASAWA × Kyupodo Collaboration Ink
This special collaboration ink brings the whimsical world of Kyupodo to life through fountain pen ink, inspired by a fictional port town known as Koberia Street: a place you might only discover by chance.
The story begins with a curious moment: following a small bird in a hat, you find yourself wandering into an unfamiliar street. There, among shop signs and quiet corners, lies Koberia - a harbor town shaped by the meeting of cultures, where Western influences, magic, and mysterious beings have quietly intertwined over time. Though not easily found, it is said that those who follow the right signs may stumble upon its hidden entrance.
Within this world, one scene stands out: a tiny shop called Ryūsei Electric, known for its enchanting “Little Shooting Star Lamps.” These miniature lamps mirror the streetlights of Koberia and are said to be powered by filaments made from shooting stars. Each lamp glows in naturally shifting hues - soft blues, greens, or warm amber - depending on the elements within the meteor, casting a gentle, dreamlike light.
This ink captures that same sense of quiet wonder and romance - like a small light glowing in a hidden street, holding stories yet to be discovered.
