I am not an avid collector and have no idea who 
either person is but yeah a mistake was made 
here. This person might be trying to take 
advantage of this mistake however. I think the 
best solution is to send the items back and give 
a refund like nesu said. If seller objects 
because the cels are damaged then well how does 
this person feel with damaged cels. if the person 
who bought them rejects then well if they are 
good enough to want to keep then what do you 
want. This definately is the best solution.
