I sold an item of Korean skincare to a customer, she asked if the item was authentic so I scanned the barcode and sent her a photo saying this was the result when I scanned it, it seemed absolutely right and I had no reason to think it was fraudulent, a week after receipt she has advised that she thinks the product is fraudulent, she says the listing showed country of manufacture as S Korea, (I’ve checked and it didn’t ), I’ve asked if she has used the product- no response yet. The item was absolutely s9ld in good faith but I am aware there area lot of fakes with Korean Beauty products. Does anyone have any idea which way this will go?
