I really enjoyed testing these!
Black – is proper writing ink black and doesn’t react well with water nor bleach which indicates that there is a degree of waterproofing and forgery resistance.
Yam-Dori, Souten, Blue, Blue Black, Nioi-Sumire, Shigure, Oku-Yama, Doyou, Tokiwa and Miraui – these are just gorgeous to look at, a delight to use, they work with bleach and blend with water easily. They are delicate and sensitive and look wonderful when used for handwriting. Just look at them! What’s not to like?
