NWT Disney Parks Pixar Monsters Inc Light Up | Mercari。Back-to-school and Halloween collide with the arrival of “Monsters University” themed light up headbands. The headband features the upper half of Mike’s “body” which is a lime green hard plastic. The predominant feature is Mike’s eye and two ivory horns protruding from the top.  Mike’s eye moves back and forth when the wearer is moving.  The eyelid also closes when you press on the right horn.  The underneath of the headband features plastic teeth to secure itself to the head. The sidebands are in the shape of Mike’s arms as if he is embracing you. The battery can be found on the back of the headband, as well as a button to light up the headband and turn it off.
