You’re looking at an apparently working Aisallin DIIER-D-10 White Gameboy Smartphone Case for iPhone 11. This came to me in a computer parts lot I bought recently. I charged it up and it booted as you see in the pics. I’m not a gamer so I have no idea how to test it further. Since I can do no more testing, I’m selling it as-is, without warranty or guarantee of any kind. It is ready to be packed and shipped as soon as payment is received. Local pickup is available too.
