In jewel cases of course! This brings me to another question: Usually, there's this plastic sleeve which has a longer and a shorter side (where you insert the HuCard). For some quite unknown reason, it's crystal clear to me that the shorter one is the up side showing the HuCard front but when I get games from Japan, they almost always have the longer sleeve side up front. Now the question, who rox the box, Japan or me? I unfortunately never paid attention how the HuCard was insert into the sleeve when I opened up a sealed game but I hope someone of you has and can tell me which is the official correct way.
