You will only receive the main unit. There are no instructions or pamphlets. Currently, sound is produced when the switch is pressed, but this is not guaranteed after arrival. Please consider this item as junk, with no returns or exchanges, including scratches and peeling on the exterior. Originally, the construction is delicate and susceptible to external pressure, and the power may turn off due to impact, vibration, or bending. This is a rare item from the golden age of Japanese electronics, and I only recommend it to those who are confident in their ability to repair issues such as poor contact.
