Calling all Apartment owners

Hey ladies,

So I moved into a small one bedroom apartment. At first it smelt fishy kinda like apartment smell. I got it to smell better.

I got some foam plated and foam cups and they started to kind of "sweat". I shook it off thinking it was the plates. Then I noticed some plastics lids in my drawer were turning a blacking gray color but it an even pattern.

I just came into my room and I left my birth control pills out and the case did the same color fading thing.

Does anyone know or had this problem?
