It is a plant-derived ink developed in collaboration with Kyoto Kusozome Research Institute. We expressed the rich colors that dwell in nature by borrowing traditional dyeing techniques. Please enjoy the changes that change with the time unique to nature.
Since the raw material of natural origin is the main ingredient, the color will change depending on the storage period and situation. After use, keep the cap firmly in place and store it away from direct sunlight and high temperature and humidity.
