The back is a molded plastic case with appropriate cut outs for all ports, and just wraps over the edges of the tablet. looks are deceiving as the case holds the tablet in place very snuggly. There is very little, if any, flex or give in this case, and there is no contact at all between the plastic case and the glass face of the tablet.
I found the magnetic front cover holds in place quite firmly, but I'm not so sure about using it for the 2 stand configurations - and that hesitation is mainly because of the weight and dimensions of the Galaxy Note Pro 12.2.
The case does add a bit of bulk to the tablet, but it's not a bad thing in my hands. Without the case, my Galaxy felt almost too thin considering the overall size. With, it feels like a slim business portfolio.
After a week of use, I've been very pleased with this case, and I would recommend it for consideration if you plan to use your tablet in an office of casual home environment.
Hope this helps folks, and feel free to drop me a line if you have any questions about it.
