Not sure what your ring size is? This plastic ring sizer is free, so you will always know your ring sizes before ordering. Instructions are on the package, but here are some tips:

-Try it on at different times during the day/night. Sometimes your fingers can swell due to temperature, after exercise, after eating salty foods, etc.

-Make sure the ring sizer is comfortable while on and can slip over your knuckles, but is not loose enough to slide off too easily.

-Email us with any questions.
