question about base set booster box

[cookymonster]

what are the tell signs that tell a shadowless from a shadowed box i sourced one and the seller wants 400 for the base set it has the wizards of the coast wrapping and he charizard has blue inner wings what does this tell you if anything and do you have any other tells thanks

 

[raichuforyou]

blue wing charizard= not shadowless
wizards shrink wrap= more than likely not shadowless
