Shining Light LED Adjustable Mask Bluetooth APP Halloween Cosplay Customizable. In order for this to work and to customize it, you have to download the Shining Mask app onto your phone. The mask then connects to it via Bluetooth and has many options. There are preset images, you can enter text, or you can upload your own files. There are some smudges to the front of the plastic, but when in use and lit up, it is not noticeable. Adjustable on the sides to fit most. The battery is rechargeable and needs a USB type C cord, not included. It charges most of the way but stops two bars short of the top. Despite that, since it is mostly charged, it does work. Measures 9 inches tall and 6 10/16 inches wide. Great for Halloween, costume parties, and cosplays. One mask does it all. Smoke-free.
