I purchased this in a 2025 Akachan Honpo fukubukuro (lucky bag), but my child outgrew it before I could really use it. As the tag indicates, the size is 50-60. It has been washed with Sarasa detergent. There are no noticeable stains or yellowing, but it has been tried on once, so please understand that this is a used item. It will be folded and shipped, so there may be creases. Thank you for your understanding.
