SNKRDUNK introduces the key points to distinguish genuine products from counterfeit ones and warns fans to be cautious when purchasing. Counterfeit products have a rough and irregular shape on the black part of the chest emblem, and the red line extends to the wing part, giving an unbalanced design. The stitching of the three stripes on genuine products is unified with white thread, while counterfeit products may have multiple colors of thread mixed together. The frame of the national flag on genuine products has a glossy print finish, while counterfeit products have a matte finish. When purchasing the Japan National Football Team's soccer uniforms, it is essential to check the authenticity of the product. Buying counterfeit products may be illegal.
