No odors. No pets and comes with Certificate of Authenticity with QR Scan Code. Because it is chanel nylon cocoon bagthe original bag and chain, the gold on the chain is a little lighter from wear compared to the Logo. I believe the magnetic clasp may have been replaced by the original owner when I purchased it. Please keep in mind it is a vintage piece and gently used, so feel free to ask questions before purchasing since the sale is Final.
