4.1. Choosing the Correct Size
For optimal accuracy and comfort, selecting the correct ring size is crucial. It is highly recommended to use a JCRing Sizing Kit before purchasing your smart ring. If you are familiar with traditional jewelry ring sizes, please note that for an optimal wearing experience with the JCRing, you may need to choose the next larger size.
