Unopened "Transformers Micron Booster Ver. 4: Eternal Showdown Edition" BOX set. I bought this for myself, but I ended up opening other parts of my collection, and this one never made it that far. Time has passed. I am selling this to organize my collection. Although it is new and unopened, I have stored it at home, and a long time has passed since I purchased it. Therefore, I am considering it a used item. I would appreciate it if you could understand this and purchase it.
