Good case

Amazing color and durability, great closure, not a lot of padding but I didn’t need it. It does not have the pencil holder but is a great iPad case over, easy fit and button accesses

Good cover for the price
Color: Black, Size: ipad 9th/ 8th/ 7th gen 10.2 inch
Perfect fit to my 9th generation iPad. It was easy to install. The back is plastic which I haven’t seen. It does what it says as far standing up with the foldable back. Seems like good quality. I gave it a 4 because I don’t know how long the back with last since it’s not standard backing.
