Notes:
When measuring the circumference, the rope must be pulled tightly, with a thinner thread (do not use a paper strip) and the measurement position is at the bottom of the finger. If the finger circumference is 55M, it is recommended to select the diameter 17#, which is 56-57MM, then the corresponding choice is to wear the diameter 18#.
In addition to 16# and 17# are standard sizes, other sizes are recommended to choose the smaller one.
The most accurate way is to go to the ring store to measure your own rin
