Note:

Please measure your finger circumference before purchasing, and then choose the appropriate size. How to measure the size

1.Take a long non-elastic rope or paper, and wrap it around your finger.

2.Make the rope or paper fit closely to your fingers to avoid being too loose or too tight, which may cause size deviation.

3.Mark the junction part on rope or paper.

4.Lay the rope or paper flat, and measure the length.It is recommended to measure multiple times for more accurate data.

Tips:

1.Due to the light and monitors effect, colors may have lightly difference.

2.Please allow slightly size errors due to manual measurement. Thank you for your understanding!

3 For best performance and accuracy, we recommend wearing the Ring on your index finger. If you prefer other fingers, the middle and ring fingers are also OK. Avoid using fingers that are narrower than the knuckles at the base.
