User blog comment:Dimachaerii/What does Ezio give Shao Jun in that small box?/@comment-1824113-20120709074119

I wouldn't have a clue what it was. It's a fairly small box, so we can rule an Apple out.

Maybe, just maybe, it could actually be some Memory Seals that Ezio imprinted himself on, but I'm just grasping at straws here.
