Can anyone answer an urgent pin trading question?

[DazedandConfused]

Hi, I am in the middle of an order on disney direct for pins. I am looking at the nightmare before christmas pins. They are in sets of 2. What I am thinking now, is do we need to trade both pins in the parks or can they be traded individually? I looked on pinpics but can't really figure out if they need to be traded together. The number on one of the sets is 34125 on pinpics. I would love to buy a few for my kids to trade but I am sort of new to pin trading. any help would be greatly appreciated. Thanks, Chris.

If the pins can stand alone they can be traded. Some set, such as a four-pin set that reads "2005" can only be traded as a set.
