Typical Taito QC, though my copy had some brown dust on the white part of the skirt. I have some gripes with this figure: the constellations on the skirt aren't visible at all unless you look closely, the paint boundaries on the purple shoe are really unclean (though this is a prize figure, so I shouldn't complain), and the eyes look strange in person. Looks fine from a distance (albeit without the constellations, which were my favorite part of the prototype), but compared to some Taito releases it falls a bit flat.
The base is an improvement upon older Taito Miku figures. It's smaller and flatter than before- shaped like a Frisbee rather than like a Petri dish.
