This is an earring made by connecting commercially available parts. Earring parts, C-rings connecting the parts, and chains are made of stainless steel. The gold plating is nickel-free. Although the parts are made with a non-allergic specification for overseas use, please consider purchasing at your own risk if you have allergies. The 100-yen coin and ruler are for size comparison and are not included in the product. Immediate purchase, silent purchase, and purchase without comments are OK! We would appreciate it if you could read our profile.
