It's a ROCK Texture Series Book Case for Note 10.1 2014. I've ordered it on eBay, pretty nice deal with a 23 € price tag and free shipping.
The case is what I've expected, leather style, is slim and looks elegant. Feels good and nice to hold it. It has no magnets - after reading many reports on magnets interfering with digitizer and pen, I've decided to go with elastic band.
Here are some pics attached for you to evaluate.
