When a seller or a service provider advertises the terms and conditions under which the seller or the service provider sells goods or specified rights or provides services through mail order sales, the seller or the service provider must not make a representation regarding the performance of the goods or the details of the rights or services, regarding information on the withdrawal of an offer to enter into a sales contract for the goods or the rights or a service contract for the service or the cancellation (if there are special provisions as prescribed in the proviso to Article 15-3, paragraph (1), this information includes the details of those special provisions), or regarding any other information specified by order of the competent ministry with respect to mail order sales, that differs significantly from the truth or could mislead people into believing that conditions are significantly better or more advantageous than they are in reality.
