How to choose the best Circular ring size for you? 

I ordered a sizing kit, what now?

Choose the Circular size that fits you

You can wear Circular on any finger except the thumb. The flat part of the ring should be towards the palmar side of your hand and the button of the ring should be accessible with your thumb. It has to fit comfortably.

If you're between sizes, we usually recommend choosing the smaller
size that slides over your knuckle. It’s better tight than loose.

Extra tip: It is best to wear Circular on the fingers of your non-dominant hand. Eg: If you are right-handed, wear it on your left hand.

Wear the ring at least 24 hours

Finger size can vary through the day, especially in the morning or the evening when your fingers are slightly larger. Wear your sizing ring for 24
hours to ensure the best comfortability both day and night.
