How to measure the size

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

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

STEP 3: Mark the junction part on rope or paper.

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