Notes
If you don't know which ring size to choose, you can repeatedly measure at the second joint and bottom of your finger to take the maximum value.
The raw material used in this ring is natural zirconia processed. You don't have to worry about the ring fading (because its color is natural).
Although this ring is marked with waterproof and anti drop features, try not to let it soak in water for a long time and frequently bump.
