Light up black sequence fedora unisex

This fedora was bought at a Michael Jackson tribute show ( Legends in concert) It has little tiny lights throughout that you can't see when it's not turned on unless your looking for them. I zoomed in on the last picture where you can see one clear tiny light if you look hard. There is a battery pack inside that can be tucked away ( batteries not included) I actually don't know what kind of battery it uses, once it wore out, we never did think to replace them. Can be cool for events, concerts, costumes, or just to be flashy when ever you choose! it doesn't have a size, but I'd say it's pretty flexible osfm. I have a large head & it fit me, it also fit my daughter who has a smaller head, so.... if you are average size or slightly bigger or smaller it should be fine:)
