You can measure the size of the ring yourself, but the error is inevitable, so you can measure it several times and take a middle value. Wrap a thin thread around your finger with a ring, not too tight, and it's best to just slide it over your joints. Mark the intersection of the rope, and then measure the circumference of the intersection of the rope with a ruler. You can find your own ring size number in the ring size comparison table. Jewelry stores can directly measure the ring size, and it is measured with special tools, and there will be no error. Measured by Darry ring, I like this ring for a long time, and the customization method is quite special. Only men can customize with their real names, and they can only send one person for a lifetime. Miss Sister, the clerk in the store, has a good attitude and the ring is very easy to use!
