The genuine double "C" will be obviously 4~5 times thicker than the outer ring, while the imitation double "C" has similar thickness inside and outside. In fact, this is more obvious, and it is an easy point to distinguish, but it does not rule out the possibility of improvement of counterfeit goods.

2. Look at the "C" in "Chanel" on the back sticker.

In fact, big names pay great attention to details. Just like Chanel's "C", it should approach a perfect circle wirelessly, not like the ellipse in the picture on the right. The genuine C is like "○" and the imitation is like "0", which is a bit difficult to observe and needs to be supplemented by fairies themselves.

3. Look at the eye shadow switch.

Adhering to the principle that genuine products will be more exquisite, there will never be a big gap around the switch, while imitations often have a wide gap like the one on the right because of rough manufacturing and other reasons.
