Even Realities - Even R1 Smart Ring Sizing Kit

The Sizing Kit is a crucial first step for ensuring a perfect fit for the Even R1 smart ring. It includes a set of non-functional dummy rings in a full range of sizes (6 to 15). Since smart rings require a snug yet comfortable fit for accurate sensor readings, this kit allows you to test different sizes in real-world conditions before committing to your final Even R1 purchase. Because finger size naturally fluctuates with temperature, time of day, and activity level, wearing a test ring helps you find the "sweet spot"—a size that prevents light from interfering with the sensors without feeling restrictive.
