This blue tag is just to prevent fake goods from being replaced by genuine goods, which is the guarantee above the goods. You can buy it for a few cents on a treasure. Unlike nike or aj's official anti-adjustment buckle, there is a magnetic stripe inside. If you are sure that the shoes are all right, please cut them when you are ready to put them on, leaving only one digestion. If it is an anti-adjusting buckle for hard goods such as Nike or AJ joint name offwhite, it is recommended to keep it.

The goods themselves do not support seven-day unreasonable return. You can only resell or contact the seller to return the goods, and you need to pay the service fee and postage. The price seems to be around 200, and you can't return it without cutting the blue label. This blue label only plays an anti-counterfeiting role.
