Obakeinu Marine Sweets safety alarm. I bought this as part of my elementary school入学 preparation, but it turned out the school would provide one, so I no longer need it. I have not used it even once, but I threw away the packaging, and I removed the battery insulation sheet. Also, I stored it outside the packaging for about a week, so there may be some minor scratches. Please be aware of this. Thank you. The regular price is 2415 yen on Rakuten Ichiba.
