I once had this question, but lxybags·ru answered it. At that time, I bought a Gucci fake branded bags on lxybags·ru. The appearance was exactly the same as the original one, and the quality was also superb. I curiously asked the seller where the bag was made, and it turned out that most of them were made in some very technologically advanced factories in Asia, especially in China.
In fact, many high-end imitation bags are made in similar places as the originals, and the technology and equipment of many factories have reached international standards.
The factories that produce these bags strictly follow the original design and even use similar materials and processes to ensure that every detail is perfect.
So, although they are fake branded bags, the manufacturing process and quality are often comparable to the originals.
