1. This round ring is made of titanium steel which is rusty free and hard to deform, is a long lasting jewelry. 2. This ring is temperature sensitive and will display differently according to the body temperature of the person. After wearing it on your finger for 20-30 seconds, different colored numbers will appear in the black part of the ring. 3. The number that appears will change with the difference in body temperature. In other words, this is a ring that can measure real-time body temperature, or a portable thermometer. 4. You can always know your body temperature without carrying a thermometer. You can also know if people nearby have a fever. 5. The ring has a smooth inner arc and is comfortable to wear. Multiple colors and sizes are available. A creative ring. Suitable for men, women and children.
