Ring size o/s意思

"O/S" in ring size typically stands for "one size" or "one size fits all." This means that the ring is designed to fit a range of finger sizes, rather than being tailored to a specific size. O/S rings are often adjustable or have a stretchy material that allows them to fit a wider range of finger sizes. They are a popular choice for gifts or for people who want a ring that can be worn by anyone, regardless of their exact ring size.
