In Japan practically all of the Transformers came in boxes, even the smallest ones like the cassettes. Some of the later cassettes were carded though. Another difference with the US cassettes is that the Japanese cassettes came with a transparent cassette case, just like the Microman versions. The box and inside of the early Japanese cassettes was the same as that of the Microman versions, except for the print on it. Also, each of the Japanese Transformers had there own number, with either a C for Cybertron (= Autobot) or D for Destron (= Decepticon) on front of it. In Frenzy's case this was D18. Unfortunately my Frenzy is in a rather poor condition and the case is missing.
