What are these yellow part on my Finn Mcmissile? Are they rust?
Zoom in closer and u can see some yellow rings on the metal part.
Why is this happening? I always store him in a closed plastic container and no direct sun light.
I haven't check my other tomicas yet but this is my favourite one (bought him 5 years ago) so I'm really worry. Should I store them in a different way?
Thanks in advance!
