ISS / Isu Product Number: PWE 43042 Earrings "Metal Allergy-Friendly" Metal Stone Earrings Nickel-Free Made in Japan for Women For minimal skin irritation and allergy-free wear. This accessory brand was created with the concept of minimizing skin irritation by considering substances generally known to cause allergies. It's a brand for modern women who enjoy life freely, feeling comfortable when wearing the accessories and excited about a new self. I received these as a gift and tried them on, but I don't think I'll wear them, so I'm selling them.
