It was there last June.
I also saw them in all four parks, I specifically remember one near Canada in Epcot. We were paying attention because different stands had different bracelets and my DGD wanted a specific one.
Thank you! My college roommate has continuously had one for over 20 years, and she can only get a few years of daily wear out of one before it falls apart. It’s been a good decade since I’ve picked one up for her.
