If you mean clothing, it is unique to rubies and does not support trading. Simply put, you can't trade. If you mean the rainbow-shaped girl in Meng Tong, you can definitely trade it. If you don't see it in the trading column, you can look at the search below and enter Meng Tong. If it is displayed after searching, it means yes. If it doesn't show, I suggest you enter a few keywords, such as children and dreams. If not, you can refresh.
