How to find your size with the Sizing Kit

After you've received the Galaxy Ring Sizing Kit, choose a sizing kit ring that fits your finger and wear it for more than 24 hours while you go about your day (including sleep). Check that it's not too small or too big. The three bumps on the inner part of the ring are where the sensors on the actual Galaxy Ring will be. Turn the sizing kit ring so that the sensors are headed toward the palm of your hand.
