Smart ring

Most smart rings on the market use aluminum alloy or plastic, but the R13 is built
with **titanium alloy**. What does that mean? Lighter (only 2.8g), stronger
(scratch-resistant and durable), and more skin-friendly (hypoallergenic). Titanium is widely
used in aerospace and medical fields — it's a recognized premium material. For buyers
who value quality, the R13's look and feel are far above its price point. If you're building a
mid-to-high-end product line, this ring will elevate your brand image significantly
