Excellent iPad case!

Excellent case! Perfect for what I needed, very stable, flexible and the color is great. I've had it for almost a year now and there's no damage or wear. Would buy again! Easy to use, stable mechanism to stand up right and wonderful color options!

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!

Perfect, it fits like a glove.
Color: 1-Navy Blue
I really liked the sleeve, the navy blue color looks very elegant and the material feels resistant but soft to the touch. What I like the most is that the back is translucent, so you still see the design of the tablet. It works great for watching videos because it stands firm when folding it, and turning off the screen alone when closing it is very practical. Because of the price it has, the quality is excellent.
