Hello. The ones with open ears are solar-powered, but neither could be confirmed to work, so they are junk items. The one without open ears is a light, but since its operation hasn't been confirmed, it may also be a junk item. They are from about 20 years ago, so they are considered rare. They have been stored at home in a plastic bag and a storage case for a long time. There may be marks from the case. Please check the photos. * A tissue is placed for size comparison. The tissue is not included in the product. The first photo (pink Haro) has stains. Due to amateur inspection, there may be other oversights. Please consider and purchase. Thank you! Please also read the profile.
