From Kaweco:
"In isolated places in the world, a dreamlike natural spectacle occasionally shows up in the nights of the spring months. In Japan, the coast in the Toyama district - which gives the new Collection variant its unusual name - the water is illuminated by a mystical blue light at this time. The rare and spectacular phenomenon is called bioluminescence and is caused by light-emitting living beings. Especially in Toyama, the spectacle is created on the accumulation of a special species of squid. The thousands upon thousands of points of light that create a captivating spectacle on the sea surface are reflected in the high-quality plastic of the fountain pen. Depending on the light, the pearl green pigments sparkle with varying degrees of intensity. The overall design is perfectly rounded off by the combination with silver elements."
Created in 1911, the Kaweco Sport is the perfect companion for on the go. When closed, the pocket fountain pen is roughly 4 inches (10.5 cm) in size. With the cap on, it grows to a standard size of about 5 inches (13 cm). Plastic body.
