About the Sailor Manyo collection:

Flowers have always been a popular poetic subject dating back to ancient Japanese history. This is the theme for Sailor's Manyo bottled ink series. Based on popular flowers frequently mentioned in Japanese “Manyoshu” – an anthology of compiled ancient poems – Sailor has chosen eight dye-based ink colors to best represent this vibrant palette range.

"Manyosyu" - Collection of Ten Thousand Leaves - is the oldest (c.759) and most revered anthology of Japan's poetic compilations. Over a period of four centuries, 4,516 poems were written by every class of person ranging from Emperors to merchants and farmers. "Manyo" is an abbreviation of "Manyosyu" and its meaning indicates people of all ranks.

"Manyosyu" is often regarded in Japan as a true expression of the Japanese spirit. The themes of the poems relate to love, elegies, nature, the seasons, and so on. Flowers are especially relevant in Japanese culture and about 1,500 of the poems in "Manyosyu" cover some 160 species of plants and 50 different flowers.
