Oura Ring Gen 4 Sizing Kit

Oura Ring Sizing Kit for Gen 4 rings. Compatible with all Oura Ring 4 models. Sizes 4 - 15 included. SIZING KIT ONLY - this does NOT come with an Oura smart ring. Box has been open and sizers worn, but essentially brand new. I'm open to reasonable offers and bundling. Reach out! Generally ship within 24 hours, unless a holiday or weekend. Comes from a smoke-free but dog-friendly home.
