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.

No instructions
Color: Gold texture
It looks nice and might work well butt there’s no instructions with it. I have a lot of crap going on in my life right now and have had no time to google how to connect this with my computer. Why no instructions????
