[Not Standard Sizing] The POBOVi Smart Ring is designed differently from standard rings, as it incorporates internal sensors. To ensure the best fit, please use the POBOVi Sizing Kit. The ring is available in sizes 7 to 11, accommodating a variety of finger sizes.
         
[How to Measure and Fit Check] Wear the sizing gauge snugly at the base of your finger, ensuring it doesn't rotate freely. For the most accurate fit, wear it for over 24 hours. The POBOVi Smart Ring should fit snugly against your skin without any rotation, so make sure it remains snug during your sizing test.
         
[Excellent Quality] The POBOVi Sizing Kit is made from high quality plastics, while the POBOVi Smart Ring is constructed from aerospace-grade titanium and features a scratch-resistant coating, ensuring exceptional durability and corrosion resistance.
