I have weird gray dots on my Airpods 3 Pro case

Hello, I got the airpods 3 pro recently, around one month ago. Weirdly, these grey little spots started appearing on them? I’m wondering if this is replaceable based on the warranty because there has been no user damage on these airpods and these spots are kind of putting me off and creeping me out. I don’t know if more are going to pop up either. I’m just kind of confused because this has never happened before.

I attached the image below through a link since i couldn’t add a picture, can someone please tell me if i can replace these? I just don’t want to go to all the way to an apple store and get denied.
