Unused SHINING APP MASK LED Mask Halloween This LED mask can display characters and symbols on its screen. It can connect to Bluetooth, allowing you to display your favorite characters from your smartphone, or even load and display images. It comes with instructions, making it easy to connect and operate. I was going to use it for a Milky Subway Max cosplay, but my plans changed, so I'm selling it. Operation confirmed. It's a system that allows you to customize it yourself. I think it could also be used to create Makina's face.
