Vintage Chanel single flap bag medium (authentic)

Bought from Amore Vintage Tokyo (well-known and reputable Japanese luxury seller). Vintage Chanel single flap lambskin black bag medium with push lock closure 1996-1997. Chain strap and hardware are real 24k gold. Comes with the authenticity card, it didn't come with a dust bag when I bought it. Shoulder bag, strap can be tucked in to be worn as a clutch too. Worn only once, too big for me (im a mini bag girl).
