Very detailed sizing rings!

Super detailed down to the grooves inside the ring so you know exactly how the Oura Ring 4 is going to fit before you buy it! They recommend you keep the sizing ring on for a full 24 hours to make sure it's a perfect fit before you order your Oura Ring 4. Also came with some freebies like Apple TV for a month free, Apple News and the Apple Health one, too.
