The size is approximately 9-9.5. It also has a considerable weight. I recall purchasing it at a jewelry exhibition about 25 years ago. I haven't used it for about the last 10 years. While it wasn't for everyday use, there are some minor scratches (scuffs) on the sides of the band. Please understand this before proceeding. It will be shipped via Takkyubin Compact. Jewelry can be discounted if purchased together.
