Jellyfish cannot swim on their own, they just drift alone the water currents. There are more than 3,000 species of them. Their jelly-like transparent bodies and their weak movements that sway in the water are said to soothe some humans. Sailor presents the "color jellyfish" pens, each one representing a Japanese species of jellyfish.
I found Iguana really friendly, helpful and efficient to both buy the pen and when I had a query - very quick to respond. The pen is gorgeous and I’m now using it every day.
