Hawaiian jewelry pair rings Men's: Size 19 Women's: Size 11 Material: Surgical stainless steel Width: Approximately 6mm Thickness: Approximately 2mm I am selling these because the sizes didn't fit. They are clean with no scratches. There are no engravings of names or anything. I purchased them for around 13,000 yen for the pair. However, I did use them for a short time, so they are not brand new. Please refrain from purchasing if you are overly concerned about this. They are made of stainless steel, so they are safe for those with allergies. The cross design is very cute. The case and box are also included.
