100% Authentic CHANEL Black Fabric Garment Travel Bag 51” X 23” X 4" 
This is a beautiful dust cover or garment bag. It folds in half and stays in place by 4 black snaps. Notice that it can hold a wide load since the sides open to 4".
There are 2 handles for carrying ease. 
Please note there are a couple of what look to be iron marks on the zipper side of the bag. They are not seen when the bag is folded.
