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.

Great Protective Case for My Mother’s iPad
Color: 2-Watermelon Red, Color: 2-Watermelon Red
I bought this case along with my mother’s new iPad, and it was the perfect choice. The watermelon red color looks beautiful with the pink iPad and gives it a very clean and stylish look. The case feels sturdy without adding too much weight, which makes it comfortable for her to carry around and use every day. The stand feature works really well for watching videos, reading, and video calls. I also like that the case supports the auto wake and sleep function, which makes the iPad feel even more convenient and easy to use. The cutouts fit perfectly, and Touch ID still works without any issues. The translucent back is a nice touch because it still lets the iPad color show through while keeping it protected from scratches and bumps. Overall, this case exceeded expectations and makes a great addition for anyone wanting both protection and style for their iPad.

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.

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!
