Very nice one! If someone can explain to me, question about Felix: is there a real limited edition after the jump of the sonic man, or is it just a "normal" production with a specific box? (With a golden medal I think...)
But why striking? What is being struck? Other than being awestruck, dont understand the nomenclature.
