Great for iPad kids👍
Color: Sky Blue
I bought this in 2023/2024 and it's still intact and usable after hundreds of food stains and me accidentally dropping it. Thank you for protecting my iPad, very great product. Otherwise, my mom would've beat my ass for breaking the iPad. PSA, the case looks the same as the picture😛

Great case for the price! Love the color!
Color: Sky Blue, Color: Sky Blue
I’ve had this case on my iPad (A16 11th gen) for a few months now and it’s held up really well. It still looks good with only a few minor scuff marks, which is expected with regular use. The front cover has a slight magnetic feel, so it stays closed nicely, and I like that it folds back to prop the iPad up for watching or typing. It’s not super bulky but still gives good protection. Also has a pen holder spot on the side! Overall, it’s a great affordable option if you want something simple, functional, and durable without spending a lot!
