I purchased this new about three years ago. The retail price was 2800 yen. I've tried several times, but it wouldn't fit in my piercing holes, so unfortunately, I couldn't use it and have been storing it. I have opened the package, but it is unused. Thank you. ↓ Below is the product description from the official website. Pierce No3 ¥2,800 (tax included) Small hoop earrings with beautiful curves. Because they are very small, they are perfect for layering with ear cuffs, etc. Made with sterling silver, they are of high quality and can be used for a long time. The easy one-touch design is also a nice feature! Material: 100% 925 Sterling Silver (18K gold plating is applied to the gold color) Nickel-free Size: 8.5mm x 11.8mm Post thickness: 0.7mm
