Give it to me straight: labels

Does the FNSKU go on the outside of the package or on product (like if it’s a monopoly game do you out it on the monopoly game or the box it’s in)

Do you need to have a UPC visible anywhere or just to have one and submit it to Amazon when you’re making the listing?

Can you remove a made in China sticker? (The one from my manufacturer is giant)

I know all this info is on YouTube and I have watched the videos I just would like to hear it from sellers not YouTubers to be sure before I make my shipment (it’s my first shipment to Amazon)
