This complete first edition set of "One Piece," encompassing all 112 core volumes plus supplementary guidebooks, exemplifies the pinnacle of manga collecting in Japan.

Released in the late 1990s, "One Piece" has since become a monumental franchise, with significant demand driven by its enduring popularity and cultural impact.

The inclusion of original promotional bands and the excellent condition of the more recent volumes enhance this set's collector appeal, while the minor aging of earlier editions reflects typical wear and further solidifies its narrative authenticity.

Given the strong historical significance and the set's status as a full completion piece, the current market price aligns well with established trends for such comprehensive collections within the Japanese collector community.
