      Perfect case
      Color: Purple Pink
      Great protection for my IPad. I’m always dropping something. This case was pretty easy to install and has the protection over the glass front. No problem using the iPad with the cover. Cute colors and has a loop to store the pen

      Very versatile!
      Color: Colorful Pink
      I got this iPad case for myself and my two year-old daughter as we both use this iPad. This case has definitely held up very well. I love the material because it’s nonslip so it’s easy for my two-year-old to hold I also love the movable and adjustable prop on the back that also doubles as a handle. There is two spots to put your Apple Pencil, so that’s very neat. It is a little bit bulky, but it is very protective and I think that is a good trade-off. There is also a cover for the charging port to prevent dust from getting in there or any spills. At first I was a little bit weary about it having a built-in screen protector, but it’s very clear and does not interfere with using the screen at all, so it’s actually a nice touch. I really love this thing and think it is worth it!
