(B) Measure My Finger Size:

Instructions:

1. Cut a thin strip of paper and make sure it’s not too wide compared to your finger width.
2. Wrap the strip around your finger where you’d like to wear the ring. Make sure it’s snug but not tight.

Tips for Measuring:

1. Measure your ring size at the end of the day when fingers are warm.
2. If you’re choosing a thick band, consider ordering a half size larger.
3. Avoid measuring your fingers when cold — they may be up to half a size smaller.
4. Avoid measuring after salty foods or alcohol, as fingers might swell temporarily.
