Keyboard and mouse combo IPAD
Color: Yellow, Color: Yellow
It’s perfect and super cheap. Makes iPad into a mini pc, mouse and keyboard lights in different colors, for under 50 dollars that’s pretty good. Considering the official Apple magic keyboard is 250.00 with no mouse, and no color on their keyboard options.

Very sparkly!
Color: Pink
My iPad fits perfectly with only a small issue that it pops out in the corners easily if not careful. I am a gently user anyway so that’s a non issue for me. It’s easy to keep clean, the keyboard and mouse work flawlessly and were easy to connect.
