How to Find Branded Replicas on Aliexpress 2025 Aliexpress Hidden Li\n<\/p>\n

However, MOQ (Minimum Order Quantity) on Alibaba is high, which means buyers cannot demand products lesser than that. For a successful online venture, retailers have to build themselves as a brand, which is possible by buying from China. A fake bag on the other hand will have the word Givenchy, but it will have rounded corners and the embossed print will not be as visible. The next method is to examine the flaps on the inside of the bag. A real Givenchy will have the word Givenchy pressed into the leather and it will have sharp accentuating lines along the edges.
