But how can they prove that's it's a real signature?

By requesting documents/ID containing the signature In question.

So, despite the fact that the box is not in perfect condition you recommend boxing rather than another method?

You've suggested boxing, not me.

Alternatively, the wrong Item received method can be used.

And even if i try dna before it will be boxable no?

How long ago did you hit the DNA?

Also if they open it and find out it's just old shoes would they ban me or start anything legally ?

In terms of the old shoes, what do you have In mind?
