Can anyone tell me if this is normal or did I mess up?
I pulled the hair pieces out and one of them came off without the joint while the other did, and the one that came off without the joint ended up having a sort of a small gap when I put it back in.
I'm fairly new to nendos so I'm not really sure..
nendoroid product number is 1431, if that helps or is of any importance

Joint did not come out with the hair piece
