This is my Ultrahuman Air smart ring size 12. Their ring sizes run differently than a regular ring.

The product is in like new condition and I purchased two covers (black & clear) and a membership plan that are typically much more. Also, this ring, unlike others, doesn’t require you to have a subscription for it to work.

With the membership (UltrahumanX), it gives you protection against accidental damage as well as credit towards the next ring you get from them.

If you have any questions about it, please let me know.
