I bought this Moko Case for my tablet.
It is made for the Galaxy 7.0 Plus.
Its a simple case but very nice at the same time.
The tablet snaps into the base of the case at each corner.
All ports/speakers/sensors are open, even the rear camera.
The base/tablet rotates 360 degrees independently from the outer
case making it very easy to switch from portrait to landscape mode
without having to change your grip on the bottom of the case itself.
It also doubles as a stand in both orientations.
The outer appears to be a faux leather, and the inner appears to be a soft faux suede
It secures closed with an elastic band.
Not bad for $20
Mine is Black, but the one pictured here is purple.
If you contact the seller, maybe you can get a black one.
Please note: There is a black Moko case on Amazon listed, but it is not the same as what I have, so I can't speak for that one. It looks like it attaches differently.
