COLMI Smart Ring - R02 Cer

Material & Craftsmanship Crafted from premium zirconia ceramic, this smart ring offers a sleek, mirror-like finish that is hypoallergenic, incredibly lightweight, and comfortable for 24/7 wear.

Note: While high-tech ceramic is highly scratch-resistant to everyday friction, like all fine ceramic jewelry, it possesses a glass-like crystalline structure that requires mindful handling.

Daily Care & Longevity Guide To keep your smart ring looking flawless and protect its internal sensors, please follow these simple care tips:

Avoid Hard Impacts: Remind yourself to remove the ring before heavy weightlifting, rock climbing, or handling hard metal tools. Direct, high-velocity impacts against hard surfaces (like granite or steel) may cause micro-cracks or chipping.

Mind the Drops: Try to avoid dropping the ring onto hard tiled or concrete floors, especially when taking it off or charging.

Storage: When not in use, store your ring in its original soft pouch or a lined jewelry box to prevent accidental knocks.

Frequently Asked Questions

Q: Is the ceramic smart ring scratch-resistant? A: Yes! It is highly resistant to standard everyday scratches (like keys or coins in your pocket). However, it is a precision electronic device wrapped in structured ceramic. Just like a smartphone screen, it can chip or scratch if subjected to severe drops or struck against hard, abrasive materials.

Q: What should I do during high-intensity workouts? A: For activities involving heavy grip work (like dumbbells or barbells), we recommend temporarily removing the ring or wearing a protective silicone band over it to prevent accidental hard impact.
