Hello!
I just bought and recieved the Intel i5-10600K, and after looking at the box i noticed that the sticker containing the product code and such were loose. This made me suspicious of the box having already been opened. Note the seal on the other opening was still intact. When I opened the package from the side of the loose sticker there was a crease on one of the carboard flapps suggesting that that have been bent. How likley do you think it is that the box was opened and the contents were messed with?
Pics for reference.
