Tray of Accessories
Within the white box are all the plastic accessories, some of which attach to Sailor Moon's uniform. (It has a section for her tiara, but her tiara doesn't actually fit in it. It seems Volks initially envisioned a tiara that wouldn't wrap as far around the doll's head. The one they actually made is too large to fit.)
I left the earrings in there, unused, because I'm not yet ready to pierce her ears.
