Purple Ring Charging Case

How to measure your finger size?

Step 1: With a strip of paper or a thread place it between your fingers.

Step 2: Wrap it with enough tightness that it is a snug fit but not so much that it restricts your blood flow.

Step 3: Mark the lines where the thread/paper meet.

Step 4: Measure the distance between the marked lines on a scale. That's your circumference.

Step 5: Compare it the sizing chart to know your ring size.
