The new limited edition from the popular Pilot Iroshizuku releases 4 colour set in 6 different themes. The colour themes are inspired by the transition of the sky of the day and night. 

Each colour comes in a 30 ml bottle. The ink bottle is redesigned to become a semi-transparent matte black bottle. Each 4 colour set comes with an exquisite display box that can be used for protecting ink bottles from dust.

This Waning Moon (zan-getsu) theme contains Tsutsuji (Azalea), Asa-gao (Morning Glory), Yama-guri (Wild Chestnut) and Fuyu-syogun (Old Man Winter).
