You can find out here. The perfect ring fit means all day comfort, and it's takes just a minute or two to find your size!

Not always! Silicone rings can wrap comfortably snug around your finger, and can roll over your knuckles, so sometimes a smaller size (than your metal ring) fits better. We recommend measuring to be sure! If your metal ring size is half size, such as Size 9.5, we recommend Size 9.

Go with the smaller size. Our rings stretch slightly over knuckles and form nicely to your finger.

We offer a Perfect Fit Guarantee. Contact us and we’ll help you get the perfect fit!

With normal wear, your silicone ring can last years. They’re made with premium, food-grade silicone and built to handle everyday life - workouts, travel, washing dishes, you name it.

Just a quick rinse with soap and water is all it takes. Avoid exposing them to harsh chemicals, and store them in a cool, dry place when not in use.
