Availability: OutOfStock

Take a length of floss or string and wrap it around the base of your finger. Mark where the floss or string first overlaps with a pen. Stretch the length of string out along a ruler or measuring tape, and take down the length in millimeters and divide it by 3.14 to get the diameter of your finger.
