If you have inadvertently purchased a counterfeit Jin Xiaohu wallet, the first step is to refrain from using it extensively, as it might deteriorate quickly. Following that, you should gather all relevant evidence including receipts, product images, and any communication with the seller. If you encountered the counterfeit in an online marketplace, report the seller to the platform and initiate a refund request. Additionally, if you purchased the wallet from a physical store, consider reaching out to the store for support or a return. To prevent future occurrences, it's vital to educate yourself on counterfeit identification techniques as outlined earlier.
