Nice, sturdy case
Color: Deep Pink
I have this case for my ipad, and I just bought one for my mom. It's sturdy and protective but lightweight. The ridges on one flap make it easy to prop the iPad horizontally and type on a keyboard (not included) or watch movies. I like the variety of colors. I got blue; my mom got hot pink. It's a good value for the investment in protecting my iPad.

Great case!
Color: Pink
Very cute! Fits amazing and feels very nice. It’s not too thick but it is protective! I bought it for my IPad A16. I got the light pink one and it does get dirtied easier but that’s just how light pink is. The fold is pretty stables. The sleep mode works well. So far I love this case! Very good for the price!

Great, once you know the trick, to getting stylus off.off.
Color: Navy Blue
The case is perfect.The only problem is the stylus holder. Apparently there's a trick to getting it out safely. And it makes all the difference in the world. Other than that, the case is just about perfect at a great price.
