LOLLIPOP TECHNOLOGY (HANGZHOU) CO., LTD Smart Ring Gen2 Sizing Kit

The femometer ring is different from a regular standard-size ring because it has a sensor inside. Therefore, before purchasing a femometer ring, we strongly recommend purchasing a sizing kit and going through a comprehensive set of plastic sizers to determine the best size for your finger. Please hold the sizer snugly against the base of your finger and do not let it rotate freely. We recommend that you wear it for more than 24 hours to accurately determine your best fit. When wearing the ring, keep the size number facing the back of your hand. For best accuracy, we recommend wearing the femometer ring on the index, middle, and ring fingers.
