Knot Theory created the first Edge Rings

Did you know? Knot Theory was the first to design bevel edge silicone rings.

In ancient times, all silicone rings were round and bulky like donuts. Then, Knot Theory came along, and designed the first edgy, slim-profiled bevel rings.

Overnight, Knot Theory’s Edge rings became the most sought after rings.

    

Now available in sizes 4~13

Today, Edge rings continue to be a favourite classic, with improved bevel angle and curved inner arc for enhanced breathability.

We’ve now added smaller sizes too, so if you want to get matchy matchy with your loved one, you can!
