Good case if you are looking for a thin and minimalistic design but the product description on the Samsung shopping site lacks details.
Described as black but it is actually clear smoke. Though it does appear black when on a black phone.
It is made from a hard but somewhat flexible plastic which enables it to be very thin. You can hardly tell it's there, which I like. However, it is very smooth with little grip and shows fingerprints badly.
If you want grip or any sort of drop protection, get one of the other cases Samsung sells. If you want thin with no button interference and the feel of not having a case, this is the one.
