Welcome to the Disney Parks Moms Panel, Michelle!
What you stumbled on is a MagicBand on Demand station. These stations, at select Walt Disney World® Resort merchandise locations, allow guests to personalize, and purchase, a MagicBand unique to them. These Bands can also be linked to your My Disney Experience Account, allowing you to use the Band for all your vacations for years to come. However, this experience is an in-park exclusive and not yet available online.
Michelle, I recently found several "stores" on Etsy offering MagicBand covers/stickers if you're looking to create a more personalized Band then the complementary Bands available as a Resort hotel guest. I also suggest taking a look as some of the newest MagicBand styles recently announced on the
Disney Parks Blog, including the all-new MagicBand Black, Millennial Pink, and Brown MagicBand featuring the Seven Dwarfs gang.
I hope this helps, Michelle! If you should have any additional questions, please let me know.
Happy New yEAR!
