Ring Size Tips：
- Our dominant hands are generally slightly larger — make sure you measure the right finger on the correct hand!
- Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
- If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.
