The closure seems to click easily bolt on me (after transportation agitated of the box), luckily it falls back into place very quickly if defeated. He fell into my manipulations, as in black plastic, it is not visible.
So a Foit the box is opened it must ensure that it is not dislocated, this has occurred since, but given the clipping system of this room, I'm sure it will happen from time to time in the future.
I thought also see the card-rays (sofflets) a little fragile in appearance (very thin mylar plastic kind), but in fact they are very well designed: If the opening is enforced but they do not tear the tabs sodilarisent the the other a stand, and snap back in place by hand quite easily.
L Dimensions: 11 x 7.4 x 2 cm (a little thick for a case for credit cards for the pockets), but no significance in non-cases.
Curb Weight: 66 g (that's not all light but reassuring when the reliability of this case).
Aluminum lined internally with plastic hull.
Note that this is not a Faraday cage, there is a small plastic lined aluminum space not in the middle of the closed shell: about 4.5 mm on 3 sides and 1 cm at the back (the hinge). We see this clearly in the pictures.
A highly recommended as housing.
