finger circumference measurement

When measuring the finger size, it is best to use a thinner rope or thin wire to measure the part where the ring is worn at the bottom of the finger (it does not matter if the finger joint is slightly larger)

yoyo Tips:
Most people don’t fit it because of the large amount
Please be sure to [tighten] the rope when measuring your fingers. It is best that the error should not exceed 1 mm.
