Can I buy a second-hand blind box without size?

When buying a second-hand blind box, you'd better make sure that the blind box has a code. If there is no code, you can't activate the blind box, you can't enjoy the services and rights provided by the government, and there are problems such as difficulty in obtaining evidence and potential safety hazards. Therefore, it is recommended to be cautious when buying and avoid buying second-hand blind boxes without codes.
