I bought this hardcover case because it was very cheap. when I got it I was pleasantly surprised (there was already negative reviews because they strictly smells ((someone wants his sandwiches to pack ??)) So, a slight odor is normal times I think and are over time here. the zipper is a little hard, but on the whole this protective bag very good and really stable because there is no soft bag and thus offers more protection !! I am more than satisfied and can recommend it with a clear conscience.
