This item was given to me over 20 years ago, and as you can see from the pictures, it has a lot of scratches and is not in very good condition. It was already used when I received it. Since I didn't purchase it, I don't know the details of where it was bought, so I won't be able to answer any questions about that. The size is probably around size 16 (Japan). The inner diameter of the ring is 18mm. There are no accessories. Same-day shipping is available. No claims and no returns, so please do not purchase if you have any concerns. Please purchase only if you understand and agree to these conditions. #MercariHalloween
