It has a light and a whistle. How about using it as a disaster prevention keychain for your child? ・Because the parts are imported from overseas, there may be dirt, small scratches, and burrs. ・The keychain, including the parts, is not very strong, so it may break if strong force or impact is applied. Please handle it gently. ・This is a handmade item by an amateur. 　Please refrain from purchasing if you are looking for a perfect product.
