In addition it can also measure the half sizes.
You can re-use it to measure your friends and loved ones fingers, or keep is as reference.
Please do not pull on the strap of the ring size while measuring, make sure it slips on easily and off your finger, like a ring would.
MEASURING YOUR FINGER:
►Your ring should be comfortable, not to tight, not too loose that it falls out.
►The best time to measure your finger is in the evening, when your finger swells up.
►You should measure your fingers at least 3 times, at different times, to make sure you have the most accurate size.
►Wearing the ring sizer through out the day, a few days in a row, will give you the most accurate measurement.
