How do you know your ring size?

1. Get a soft string (not stretchable) and a marker pen. |
|
2. Wrap the string around her finger on the knuckle, and do it not too tight or too loose. |
|
3. Mark the string that crosses one another |
|
4. Place to a ruler in mm. |
|
You can know the circumferences of the ring and from here we can check the size.
