This may have been the first Japanese shirt pocket radio to make use of a clever reverse-painted plastic trick: adding a 1.5 mm (1/16") lip around the edge of the reverse-painted area, giving the clear plastic face the illusion of extra depth. Other radios that used this same technique included the Harpers 6-transistor and the Daylite TN-603, plus all their many variations and AKA names.
