WHEN YOU DON'T KNOW THE SIZE

Using a ring that fits well, simply measure the inside diameter using a ruler in millimetres. Using the chart above simply identify the size that matches your measurements. 

Determining the size can be done a number of ways, including sending samples. Please contact us if you would like further assistance with this.
