Here is a cool vintage Chanel duffle bag.

I bought this preloved, I do not have more information on its authenticity. It was sold to me as vintage Chanel, and I was told it was from their 90s sportsline.

There is no code sticker. It was purchased as is, preloved.

Check out the last picture for a similar vintage Chanel bags sold on a popular international sales platform. Do your own research.

Bag remains in good vintage condition. Some signs of wear consistent with its age as vintage.
The zippers are missing the pulls.
Can be replaced with generic ones at your local shop.
This was a common practice luxury brands did in the 90s and Y2K - take off the brand zipper pulls and code stickers when discarding unsold / excess goods.

The bag is sold as is. You can check photos and do your own research online.
