Specific measurement methods:
Please use a thin line or paper strip to measure the circumference of the finger wearing the ring, and select the number corresponding to the size chart above.

1. Use a thin, non-elastic rope.

2. Make a circle around the place where you wear the ring and tighten the measuring line.

3. Use a ruler to measure the length of the rope.

Precautions:

1. Use thin paper strips or ropes to measure the position of your fingers. Do not measure the finger joints. Make a mark where the paper strips or ropes overlap.

2. During the test, be sure to tighten the paper strip or rope, measure multiple times and take the average, and control the error within 1MM to avoid abnormal differences.

3.Because some customers may not measure accurately, we usually send them the size they choose, but we may also send a larger size to avoid being unable to wear it!
