A plastic tool that allows you to measure your ring size yourself. The ring sizer is made of plastic and the sizes are based on the North American chart (Canada and the United States).
The ring sizer is easy to use; simply fold it back on itself and insert the end where there is a small arrow. Once properly adjusted, the arrow will point to your ring size. The ring should encounter a little resistance at the knuckle when you try to remove it, but you shouldn't have to force it.
Keep in mind that our finger sizes vary from season to season. In summer, our fingers tend to swell in the heat, while in winter, they shrink in the cold. Keep this tool in your jewelry box, as your ring size may change over time.
For a wider ring, you need to take a larger size, otherwise the ring will not fit over the knuckle.
If you have any questions, please do not hesitate to contact me. I will be happy to help you find the right size for you.
