This is a sealed booster pack of the Shin Megami Tensei Digital Devil Story Trading Card Game. Specifically, this is Part 6 (Chaos Masquerade) of the 9 parts of the original SMT TCG. Part 6 is one of the most rare boosters for this game, along with parts 8 and 9, and I have looked for months to be able to acquire more than one. Even more than the other cards I have listed in the SMT TCG, these are very limited and once they are sold I am not sure if I will ever be able to find more for sale. The price of this item reflects the scarcity and the difficulty in finding replacements. 

These are a rare, vintage, Japanese trading card set. Card names and descriptions may not be in English. The packaging indicates there were 333 individual cards available in this series of the game, though due to scarcity I recommend keeping the pack sealed rather than opening. 

I have many Shin Megami Tensei Trading Card Game items in my story including sealed booster packs and even starter decks! Please feel free to check out other items and message me about a custom bundle with a bulk discount/combined shipping if you are interested in ordering multiple pieces! Thank you for looking
