Contents: one sizing ring tool
Compatibility: designed for Ultrahuman smart ring sizing
Material: lightweight sizing material suitable for fitting
How to use
Slide the sizing ring onto the finger you intend to wear the Ultrahuman smart ring on and check for a comfortable, secure fit. The ring should sit snugly without causing discomfort and should be able to rotate slightly but not slip off. Try the sizing ring at different times of day and in different temperatures if necessary, because finger size can vary.
