Complete boxed celadon vases crafted by Kosugi master Ikegami Eiichi are scarce on global auction markets, only a small number enter circulation each year. Hand-thrown into plump rounded bottle form with tiny neat flared mouth, perfect for traditional Japanese Ikebana flower arrangement. The inner recessed foot bears Ikegami Eiichi’s exclusive maker stamp as permanent authenticity proof. It comes with its original hand-inscribed tomobako wooden box with master’s brush calligraphy and red ink seal. Most exported vintage Kosugi wares lose their matching original boxes, so intact archive sets carry prominent collector value. Preserved in absolute mint unused condition, free of chips, cracks, glaze peeling and surface wear. This scarce celadon flower vase is highly desired by Japanese Ikebana practitioners and East Asian celadon antique collectors worldwide.
