Description

With the Oura Ring 4 Size Kit, you determine your Oura Ring size. The size of an Oura Ring is different from a standard ring size. Make sure to order this size kit first before ordering an Oura Ring 4. This way, you can be sure that you'll buy the correct size. You'll receive the purchase amount of € 10 back in the form of credit. You can use this credit when you buy an Oura Ring 4 at Coolblue. This makes the size kit free. Make sure to wear the trial ring for 24 hours, as this ensures you know if the size is comfortable. The Oura Ring is most accurate when worn on your index finger. Is it uncomfortable? Try the ring on your middle or ring finger.
