Great case for the money
Color: Tea Brown
Love the case. Installation was an easy Perfect fit. The leather seems to be fairly scratch resistant. which was important for me working construction. I do not have an Apple Pencil so I can not speak on that portion of the case. The keyboard back light changes colors, I prefer to keep it on a softer setting. It doesn't take long to charge, and connects via bluetooth seamlessly . The magnet could be a little stronger, but it does work fine.

Protect Your iPad
Color: Tea Brown, Color: Tea Brown
Perfect case for my iPad! I love the leather feel of the case especially for professional work settings. The exterior pocket is helpful to hold business cards or any document. I’ve had no problems with the case. The magnetic component keeps my tablet secure and the tablet stays in place when adjusting it. The keyboard connects via Bluetooth and I love that it has different colors to choose from. The light does not stay on the entire time, but it has a button to click on when you need the keyboard backlight on. I don’t use my iPad frequently but this case gets the job done. I always take it with me on flights without an issue and my tablet is always protected.

Affordable and Stylish Folio
Color: Blossom
Things to note: They keyboard requires charging. The keyboard is loose in the folio. For some reason I assumed it was attached. It's not unusable but a little tricky. I would have preferred it anchored into the folio. The folio itself self is lovely and well made. The keyboard feels like I better baby it or one wrong move and I might end it. I wouldn’t recommend it for heavy handers but I do appreciate the feel and lightness. I do wish I had listened to my husband and sprung for a pricier model with pass through charging but for the budget I feel I’ve gotten a good deal on a very elegant looking and functioning case.
