Although unopened, please understand that this item has been stored at home for a long period. Since it is unopened, we have not checked its operation. We will also use recycled materials for packaging. We inspect the items as carefully as possible, but due to amateur work, we may overlook small stains. We appreciate your understanding. Please note that the color may differ slightly depending on your monitor. We may change the shipping method from Yu-Yu to Raku-Raku as needed. (If you wish to change from anonymous shipping to another method, please consult with us in the comments.)
