I love the Volks Midis which are 25cm but they stand a TEENY bit taller than the Obitsu 25cm. (I've never measured both to see which one actually IS the 25cm on the dot!) They're a bit more mature looking than the Obitsu 25cm and they're very poseable! I have at least 50 of them on my own girls. (I do not like my 1/6 girls as tall as the 1/6 guys, so I always opt for the 25cm bodies for them when possible.)
All the Inners and Moon are the 25cm Volks Midi: (Saturn is the 25cm Obitsu; Neptune/Uranus are Volks 27cm and Pluto is an Obitsu 27cm; Starlights are Volks EBN Maker and Volks EBC Fighter and Healer; Tux and Andrew are Volks EBN 27cm; Chad is Volks Neo Goh Guy 28cm; Greg & Ken are Volks EBC, and Sammy is an Obitsu 25cm converted boy. Asteroids are 23cm Volks Mini EBA & EBB, Chibi Chibi is an Obitsu 11cm)
Sailor Moon and Mercury are the 25cm Volks Midis:
All the girls here are 25cm Volks Midis, except for lady with blonde hair, a fur stole and lavender gown and the lady with the black-brown ponytail but she's hidden way in the back anyway so you can't see her):
Hino Kahoko is a 25cm Volks Midi, next to Tsukimori Len, a 27cm Volks EBN:
Serenity is a Volks 25cm Midi, while Seto is a 27cm Volks EBN (made to be about 28cm by pulling his knees as far apart as they can go without coming apart.):
