[IDK] real or fake ? Bought them from Walmart today !

The AirPods weight 11 grams together and the case is 51 grams. I did try the find my feature and it makes sound. The find my also updates itself when I am further away. Didn’t get to text it from too far but it went from 0.0 miles to home when I came back to my room. I think they are real but just want to confirm one more time.
