Omilly Ring Size Adjuster for Oura Ring Gen 4/3
Is your Oura Ring too loose and slipping off your finger during workouts or sleep? Omilly's invisible ring sizer solves this problem without damaging your smart ring. Designed specifically for Oura Ring Gen 4 and Gen 3, our adjusters let you customize the fit at home, no professional tools required.
Custom Fit for Smart Rings — The adjusters are precision-shaped to match the inner curve of Oura Ring 4/3, avoiding contact with the sensor area to ensure accurate health tracking.
Dual-Style Kit for All Needs — 60pcs self-adhesive stickers (cut to any length for temporary fit) + 2pcs upgraded durable inserts (for long-term stability). Choose the style that works best for you.
Skin-Safe & Non-Irritating — Made of soft, hypoallergenic material that feels smooth against your skin. The low-profile design stays hidden inside the ring, so no one will notice it.
No More Costly Resizing — Skip the hassle and expense of permanent ring resizing. Adjust the fit yourself in minutes, and remove or reapply the adjusters whenever needed.
Built for Active Lifestyles — Whether you're climbing, running, typing, or sleeping, the adjusters keep your Oura Ring securely in place, so you never miss a health metric.
