This is an adjustable, free-size ring made of stainless steel. (It's also recommended to wear it with the No. 12 necklace ✨ They have a similar design ✨) ★ The size at the time of listing is approximately size 16 (Japan size). ★ When adjusting the size by widening or shrinking the ring, please be careful not to injure yourself as stainless steel is a hard material. Use a cloth or similar material for protection. ★ If you have any concerns about the width, current size, or any other questions, please let me know in the comments before purchasing. I will do my best to answer them. ☆ This product is allergy-friendly, but please understand that it may not be completely hypoallergenic. #ring #rings #stainlesssteel #stainlesssteelring #metalallergyfriendly #metalallergy #allergyfriendly #fashionring #gold #silver #freesize #freering Color: Gold-toned Material: Stainless steel Size: FREE
