Thank you! I've just contacted the seller and she insists that it is authentic and told me to have it checked at a physical store. She also said she bought it at a US warehouse store. Should I have it authenticated at a physical store?
There is no MK warehouse only outlets is that what she meant? I don't think MK authenticates but you you can try taking it to compare. You can also compare using Selma bags already authenticated in this thread.
