It's still unopened! I'm selling it because I haven't had a chance to wear it. It doesn't have a tail or anything on the rear, so I think you can wear it even after Halloween is over ♡ It would cost 10,740 yen including shipping if you bought it from the official store, but since it's unopened, it's this price. Please understand. Please refrain from purchasing if you are overly concerned about details.
