Sailor Pen x Tsubame Note Collaboration 2019 Limited Edition Fountain Pen Ink "Kokihanada"

This is a 20ml bottle of Kokihanada ink for fountain pens, originally included in a limited edition gift set released in 2019, a collaboration between Sailor Pen and Tsubame Note.

Kokihanada is a traditional Japanese color, a deep, beautiful blue. This is a water-based dye ink made in Japan (refer to the second photo for reference, quoted from the introduction site).
This listing is for the ink only; the fountain pen and writing paper are not included.

The item is new and unused, but has been stored at home for a long time.
