Observe the small circle mark, check the mark and other methods.

1, observe the small round mark: the genuine dot is colored, and the fake is a black letter.

2. Check the tag: the genuine tag is hard, not easy to bend, and the font is printed evenly. The item number of the label is the same as the code of the circular label inside the waist. There is an internal silver anti-counterfeiting chip under the tag sticker. When the sticker is torn off, the anti-counterfeiting chip will stick to the sticker and tilt up together, but the fake does not have an anti-counterfeiting chip, or it is only printed with the pattern of the chip and cannot be torn off.
