"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.

Flowers are especially relevant in Japanese culture and about 1,500 poems in "Manyosyu" are about flowers. Sailor has therefore chosen to base the colors based of their new Manyo ink bottles on flowers mentioned in "Manyosyu" poems.

The ink bottle contains 50 ml ink.
