COngratulations on your Chanel purchase! They have great bags.
Each Chanel bag should come with its carte d' authenticite and a number would be indicated on the card which corresponds to a hologram sticker inside the bag. zippered pull is usually inside the bag. and the chanel bag should come in its box and sleeper bag.
NM is an authorized seller, so their authenticity is unquestioned, otherwise theyd get a huge lawsuit if they send fakes!!
