Pusheen Mermaid shops Enamel Pin - Rare

Product Name: Pusheen Mermaid shops Enamel Pin - Rare
Please read: I think it's in great condition BUT it has been displayed on my board for about a couple of years. I live in a humid climate, so the metal may be oxidized in places or completely, I'm not 100% sure how to tell. It's my understanding oxidation can always be cleaned and restored but I would prefer its new owner do that if they so choose as I'm not very experienced or knowledgeable with that. I'm being upfront about this because I have bought pins that were oxidized and not disclosed by the seller. Still, the vibrancy of the colors hasn't changed since I came to own this beautiful pin. Pin may contain slight shops scuff or scratch marks. I've taken amazing care of my pins but may have normal wear from previous owner or may have originally been purchased as a B-grade or lower. Pin sold as is.
