I have a few Disney buttons (not like the big ones you get from the parks). I was wondering if people buy/ sell/ trade those. Also, should you/ how do you add them to PinPics? One of them in a Moana pin that I got from a Disney Animation Tour event, one is from a story in Downtown Disney (so I guess it doesn't count as official?), an one Lion King button that I received as a gift. What's the proper course of action on documenting these and/or exchanging with other people?
