I purchased this custom-made item from a handmade artist in the summer of 2024. I've used it about 3 times. Purchase price: 2800 yen The metal parts are surgical stainless steel. The pin is slightly bent, but it doesn't affect wearability. Please check the photos for the size. If you're interested in purchasing, please read my profile. I also have a long necklace and ring made of the same black lip pearl.
