The console snaps in case a continuous and this places almost like a second skin to the DS. Slots remain open completely, the wrist strap may stay on. Open comes as no case also.

A deduction of points, I give because of packaging: Must soo necessarily much plastic garbage generate the Case to protect? This to "break" the package is already a real act of violence.
