Two body piercings. I believe the material is zirconia. I used them as earrings, not as body piercings. I think they are a little thicker than the first piercing size. They are resistant to rust, discoloration, scratches, and sweat, and I had no problems wearing them constantly. I think they are in good condition. I bought them a long time ago at Shibuya 109. For those who understand that these are used items. Body piercing, navel piercing, ear piercing, women's, zirconia
