It is NOT leather, but rather a cheap plastic, stuffed with some sort of flimsy card, the protective strength of which I seriously question.
The worst part is the clasp.. for no reason I can imagine it is magnetic rather than a physical attachment. A stupidly weak magnet -inside- the lining that does not have enough force to stay together so regularly pops open. Can't imagine it haven't any security at all in a bag or drawer.
Even when closed the front cover slides around, exposing corners and edges of the kindle itself.
