Look at the outer packaging and the small packaging inside.

1. Observe the outer packaging: Observe whether the outer packaging of the blind box is damaged or stained, and whether there are numbers or barcodes and other marks. These marks help identify the specific contents of the blind box and minimize the purchase of the same content probability.

2. Observe the internal small packaging: After opening the blind box, observe whether the internal small packaging is intact and whether there are traces of being unpacked or repackaged. These are used as the basis for judging product quality and authenticity. .
