A. Push the end through the buckle to form a ring shape on your finger
B. Put the sizer onto your finger. Adjust to a comfortable fit. It should slide on easily and be snug to take off over the knuckle.
C. Read off the size indicated by the arrow and that is your size!
Note: TEMPERATURE IS IMPORTANT. If your hands are hot or cold it will affect your ring size. Cold finger shrink while a hot finger expands causing an inaccurate reading.
