There is a special Disney FairyTales pin trading event at Epcot from August 9-11, 2019. At this event, which costs at least $150 per person to attend, they will have a special Limited Edition themed MagicBand for sale. There will only be 1000 made and the cost will be $34.99. As I get more details and better pictures, I’ll post them here.
This MagicBand is not available online from Disney, but you can buy it from eBay online by clicking this link which will take you right to the product listings (if any are available).
