There are three new MagicBand On Demand graphic designs out today for the new Disney+ Star Wars show The Mandalorian. Two of the bands feature The Child (a.k.a. Baby Yoda) and the other is of IG-11. You can only find these designs at On Demand kiosks in Walt Disney World.
This MagicBand is not available from Disney directly online, but you can buy it from eBay by clicking this link which will take you right to the product listings (if any are available).
