After a number of years, the Sailor Pen Company has decided to revamp the ink bottle of their well-known Colors of Four Seasons Jentle Ink - Bottled Ink line. The elegant 20ml square-bottle that has proven to be popular for the four newer colors within the Shikiori Bottled Ink line (Yozakura, Yodaki, Yonaga, and Shimoyo) will also replace the current round-bottle that feature the original 16 Colors of Four Seasons Jentle Ink colors.
