Extended data

Matters needing attention when measuring dimensions:

1, if you want to get a more accurate size, you can measure it at 19: 00-2 1: 00, because the finger size is the most accurate at this time;

2. Don't measure your fingers when the weather is too cold, because the size of your fingers is the smallest at this time;

3. When the specific size number cannot be determined, you can choose a larger size (half size or 1 size);

4. Adjust your number according to different seasons and buy a ring in winter. Because of the cold weather, your fingers are one to half thinner than those in summer. It is advisable to rotate the ring left and right after wearing it, but it is not easy to fall off. It is advisable to feel a little tight after wearing it in summer.
