Design Features

Shell material
The outer ring is as gentle as jade, with a stainless steel shell and tens of thousands of CNC grinding and polishing operations to achieve ultimate durability.

Thin and light design
Innovative and non-sensory wearing, with a thickness of 2.7mm, the design is lighter and thinner, making it more comfortable and convenient to wear.

Inner shell material
The inner ring is tough and durable, while the smooth inner shell uses hypoallergenic epoxy resin for a quality feel from the outside to the inside.
Size Measuring Tips

STEP 1
Take a long, non-elastic piece of rope or strip of paper and wrap it around the finger you want to size.

STEP 2
Ensure the rope or paper fits snugly — not too tight and not too loose — to avoid inaccurate measurements.

STEP 3
Mark the point where the rope or paper overlaps (the junction).

STEP 4
Lay the marked rope or paper flat and measure the length between the marks using a ruler. It's advised to measure multiple times for better accuracy.
