These tips are a starting point, not a complete method
The checkpoints described here are commonly cited reference points, not a foolproof test -- the most sophisticated counterfeits reproduce even these details convincingly. For a high-value item, pairing these basic checks with a professional authentication or a marketplace's own inspection service is the safer approach.
Extra caution when buying from an overseas seller
Buying directly from an overseas individual seller adds risk on top of the usual authenticity concerns, since a return or refund is often much harder to arrange once an item has crossed a border. Checking a seller's reviews and return policy before paying, and preferring a platform with buyer protection when possible, reduces that added risk.
Frequently Asked Questions
Can these tips catch every fake?
No. A well-made counterfeit is often extremely hard for a non-expert to catch by eye, so treat these as a basic first check and leave the final determination to a professional authentication service.
What if I compare it to a genuine item in a store and I am still not sure?
Requesting a professional inspection from a resale marketplace or an independent authentication specialist and getting a formal certificate is the most reliable way to resolve that uncertainty.
