Just got a Chanel Caviar Jumbo Flap from the Chanel store in the US and it came in a white gift box rather than a black gift box with a description of the bag. The box has a white top with black chanel words and a black base. This box seems sturdy than the normal black gift box but I've never seen it. Is this normal? I've never seen a white gift box and am wondering if I should go back and get the black box.
