NCSX has a defective Momohime fig for $90+s/h. It sounds like it should be easily fixable. I don't know what to do gaf, so I'm posting it here hoping it will be sold out before I cave in.

New Momohime 1/6 scale figure from Alter but her head's loose and doesn't appear to have been glued properly to her neck at the factory during the manufacturing process. The bottom of the head plugs into the neck socket and a simple application of glue should make her as good as new. Please note the packaging has been opened to check the other parts of the figure and everything else is intact. Sale price: US$90 + shipping.
