Finding a Silicone Ring Size?

Luno rings are made from premium medical grade silicone, a tough as nails, yet flexible material. Currently we only sell whole ring sizes (i.e. 5, 6, 7, 8 etc). If the ring size chart shows that you are between two numbers, it’s recommend that you order the smaller size.
Why? : Silicone rings relax after a few days of wearing it. If you order the bigger size, you may find that your ring may seem to be the perfect size when you first start wearing it, only to loosen after a couple of days. On the flip side, a smaller ring may feel a little tight in the beginning, but will often relax for a perfect fit.
