Just got the heels and had a few questions. First off though these are really neat and make her so much more stable. Ok. 1: as others have said the ball joints are pretty loose so I was wondering how exactly to do the glue treatment. Am I supposed to apply the glue in the socket? Or to the ball joint itself? and 2: It says that the print would be printed in black nylon plastic but when removing the pieces from the sprue and trimming away the excess there are small white spots where it was trimmed. I had thought about giving the parts a light sand to reduce the graininess but now I am hesitant cause I don't want the black disappearing.
