I just received some Disney pins that I ordered from Ebay. I had a couple of questions. On the back of the pins, it says made in China, can I trade these when we go to Disney? Also, one some of them, it says Hidden Mickey 7 of 8 or another one says 1 of 4, does this mean that I can't trade it unless I have all of the numbers? Any help would be great, I am new to this pin trading and want to make sure that my son has pins he can actually trade. The person from Ebay said that if there was a problem to email them. Should I?
