The Cocktail Series is a collection of fountain pens themed around cocktails, which began in 2011.
The 2020 edition, marking the 10th release in the series, is named "Cray Azure," meaning "Clear Blue of Kure and Seto Inland Sea."
This pen is inspired by the Seto Inland Sea and Seto lemons from Kure City in Hiroshima Prefecture, where Sailor Pen originated.
The pen features a vibrant two-tone clear blue with lemon yellow accents, making it a fitting celebration for the series' 10th anniversary.
