Dior Sauvage 3x30 ML legit check source unknown

Hello everyone, my friend has bought a 3x30ML sauvage tester which look kinda sus to me. Ive been unable to find a 30ml bottle of sauvage which has a cap that is not of the same radius as the bottle. Also the cap is not magnetic. I was planning on buying a decant from him but then before that ive come to take your guys' opinions. Asked him where he got it from and he said his uncle bought it from somewhere idk
