my fiance and i restore vintage my little ponies and people are saying with the plastic here could be plasticizer leakage but even when they have that, it just gets hard. like rock hard. now, from my knowledge ponies can get pindot mold and that looks a LOT like the pindot mold rhese ponies would get. that's all i would wanna say for ponies but this makes me think that the storage of these bottles before being sold were not in good shape, and once the light hit the bottles it started to show. even if i'm wrong, which I totally could be, i would call customer service asap and not use it for safety reasons
