Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.

Bright & Pretty Hot Pink.
Color: Pitaya Red, Color: Pitaya Red
Very pretty and bright. It’s thick and great quality. Strong grip and doesn’t come off easily. Easy to clean when it gets dirty. It also has a nice backing. I prefer the transparent bright pink backing than the clear version. I love the strong magnetic for when I position it upwards. It can be positioned downwards too.

Very protective iPad case
Color: 1-Navy Blue
This MoKo iPad case is excellent! It fits perfectly and provides great protection without adding bulk. The navy blue color looks very sleek, and the translucent back shell is a nice touch. It’s super magnetic, with great padding. The smart cover works flawlessly with the auto wake/sleep feature, and the cutouts line up perfectly for Touch ID. Lightweight, durable, and a fantastic value!
