To find very practical and not everybody Case is the Sleep / Wake function by closing and opening the lid.
The real leather is processed very clean. All necessary ports are accessible. The case provides a very good all-round protection. Really Good.
Addendum;
I had (for the wife) ordered me to my 2nd OnePlus another case in the color cognac. That's just super fit, it's from another leather, very fine and looks great. The black case is made of open-pored leather, in this case better for men's hands.
