I am selling a Saint Laurent style bag. It is the Sac Du Jour style in the nano size. I am unsure about the authenticity of the bag which is why it’s priced so low. I am unable to find a serial number and this bag was given to me by a friend. It’s a great throw around bag that looks just like the real deal! There is no dust bag with it. It is in excellent condition and has no major flaws or signs of wear. Feel free to send me any questions or offers!!
