Popular! Ring Gauge! The reason it's chosen is the magnifying loupe at the front, making the numerical values on the scale easy to see!! Set of 2 【Sizes】: Measures from Japanese standard sizes 1 to 33, Japanese standard sizes 1 to 33 【Clear Mark】: Japanese ring size adjusters have clear marks, making the guide chart easy to understand, and allowing you to get the correct size without the help of an expert. 【Measurement Notes】: The weight of the ring gauge itself can create a gap between the finger and the gauge, resulting in a size that is looser than the actual size. If the second knuckle is thicker than the fleshy part of the finger where you wear the ring, a size that allows the knuckle to pass through easily is the appropriate size. The size of your finger may change depending on your physical condition. TA-4-2-20
