How to choose the best Circular ring size for you? 

- The ring comes in 8 different sizes from US 6 to US 13. One of them should fit. We don't do half sizes.

- The Circular ring sizes fit the standard ring sizes. If you already know your ring size, Circular sizes will be the same. You can also go to any jeweler to ask for your US equivalent size.

- Here are some wearing recommendations: You can wear Circular on any finger. It has to fit comfortably. If you're between sizes, we usually recommend choosing the smaller size that fits. If you have big knuckles, choose the smallest size that slides over your knuckle. It’s better tight than loose.

- 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. Note that the three middle fingers give the most accurate readings. Finger size can vary depending on the time of the day, especially in the morning/evening when your fingers are slightly larger.

The flat part of the ring should be towards the palmar side of your hand. 

The button of the ring should be accessible with your thumb.

USE

In case the ring gets stuck on your finger:

1. Push the bottom of your ring towards your finger, it should create a space above your finger, between your finger and your ring. Then pull the ring to tak it out while continuing to press towards your finger.

2. Use cold water with soap or gel and slowly twist the ring to remove it.

3. Hold your hand up above your heart until the blood pressure lowers and then try to remove your ring.

Watch out, finger size can vary through the day, your fingers may swell in the morning or evening!
