As shown in the photos, the contents are the following three items: ・Main unit (White & Natural) ・USB cable ・AC adapter There are no instructions or box. The main unit, cable, and adapter have no noticeable scratches. The box, however, shows some signs of aging. Please check the Trigo website for compatible standards, etc. ※ When inserting the cable into the main unit, it may be difficult to insert due to the curved shape of the unit. Even if you think it's inserted, it may not be fully connected. Please insert it until the lamp lights up. Thank you for viewing.
