How to measure the inner diameter of a titanium steel ring?
method one:
When measuring, put 4 long fingers (except the thumb) to the 'tiger's mouth', squeeze it tightly, and then measure with the measuring tool, for example, it is just 45mm, then, adding 2~3mm on this basis is suitable for you Circled. This specification will feel a certain pain when wearing it, please use hand sanitizer and other lubricants to lubricate. Some people like to wear it a little looser, and they can choose a slightly larger ring.
Method Two:
When choosing to wear a jade bracelet, you should be able to put the jade bracelet into 4 long fingers (that is, except the thumb) and to the 'tiger's mouth', it feels a little tighter, then remove the jade bracelet and measure the inner diameter, for example, it is exactly 55 mm, then, this size is suitable for your ring. Some people like to wear it a little looser. When choosing, choose a ring that is 1 to 2 mm larger, so that it can be easily put on and taken off.
