Sailor's Manyo inks range is named for 'Manyosyu', the 'Collection of Ten Thousand Leaves', which is Japan's oldest and most revered anthology of poetry.
Dual shading inks shade different colours than their base colours when pooling into the areas of high and low concentration on the page.
Therefore, dual shading inks are really fascinating.

Manyo 'HINOKI' shades from blue grey to purple and green.
Manyo 'FUJI' is a light purple that shades to different purples.
