This is an adjustable, free-size ring made of stainless steel. ★ The size at the time of listing is around size 16 (Japan). ★ 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 questions about the width, current size, or anything else, please let me know in the comments before purchasing. I will do my best to answer your questions. ☆ This ring is allergy-friendly, but please understand that allergic reactions are not always completely avoidable. #ring #fingerring #stainlesssteel #stainlesssteelring #allergyfriendly #antiallergy #allergycare #fashionring #gold #silver #freesize #freering Color: Silver系 (Silver-toned) Material: Stainless Steel Size: FREE
