The Light-Up, Glow in the Dark Spider Web Ears were released as part of the Mickey Mouse Light-Up Skeleton Costume Accessory Set for Adults July 27, 2020 on shopDisney.
The ears are a little more lightweight than standard ears and feature the long shopDisney tag attached to the back of the ear (like several Disneyland Paris Ears). The power button for the light-up portion is on the back of the other ear. ￼The ears come as part of a set with the light-up skeleton Mickey Gloves (which run incredibly small).
The set’s original retail price is $29.99.
