Spinner Ring转环

What it is

A spinner ring has two parts: an inner core that sits on the finger and an outer band that rotates around it. Some use bearings, others a simple sliding fit.

Why it matters

It is the most discreet fidget: you can spin it with your thumb in a meeting. Fit and smoothness matter more than speed.
