You will receive two main units, one unused earphone, and one homemade case. The case is a modified business card holder and can be used with the included earphones attached. There are no instructions or pamphlets. There are scratches on the exterior, and peeling due to hardening of the double-sided tape. One unit's switch turns off with a slight impact. The other unit's switch also turns on. Since these are old items, I cannot guarantee full functionality after arrival. Therefore, please consider them as junk, sold as-is, no returns/no refunds. These are rare items from the golden age of Japanese electronics, and are recommended for those who can fix issues like poor contact themselves.
