Is this something an adult would really rock in public? Just curious....non judgement.
I'd wager MANY adults would....and those that would probably don't care what others would think. There are plenty of unique personal styles out there. There were a a few threads in the Apple Watch section a while ago asking if a male would wear a pink band. What's strange or odd to one person may be completely normal to others....
People rock what they want.....And in urban areas, I've seen some styles that the mainstream might question but most are comfortable in their own skin & own their style.
I'd have no problem wearing these in public. There's no way I'm paying for them, but I also wouldn't be self conscious about wearing them in public.
These are equivalent to PS4 or Xbox special edition consoles.
Second, you'll have collectors picking these up. As another poster stated, Disney is going big with this Mickey 90th.
There are multiple companies that have Mickey themed limited editions planned. From food based (Ice Cream Brands, Oreos, Goldfish, cereals to clothing retailers. There's a new art exhibit in NYC & major train stations in France are going to be overplayed in art. There's a touring show happening in Japan, etc. These are just the things I found by googling.
Obviously, the average person probably isn't going to be in the market for these anyway....
