Absolutely love the Warrior of Serenity ring! It was well worth the wait time! Fantastic quality and craftsmanship with the engraving.
They're perfectly adorable, high quality and perfectly made. So happy I get to honor my Celtic heritage and have a functional beautiful ring for work. Highly recommend!
Met and exceeded my wife and I’s expectations. Thank you, Knot Theory!
I love the color of this ring, it matches so many things. The fit is so easy you don't even know you have it on. I would highly recommend.
This ring is delicate and comfortable. The lace pattern is intricate and adds a touch of elegance. Ideal for everyday wear or special occasions.
Fantastic color, great fit, and overall fast shipping! Material is soft and comfortable.
I saw the Rune stepped ring and had to get it. It looks great. I purchased it in Silver and am not disappointed at all in how well it looks. It will also be a lot more comfortable while handling things like shields, axe and swords or even when just working out or other chores.
You're not gonna believe how comfortable and soft this silicone ring is from Knot Theory 🤗😍 I am obsessed with this Northern Lights metallic color I chose. This ring is so easy to slide or roll onto your finger instead of having to stretch it.
I got this for my husband to wear at work for a wedding ring. It’s perfect! He loves it so much he wears it all the time! It actually looks metallic!
I got my boyfriend a silicone ring on his bday and he's obsessed! He hasn’t taken it off, says it’s super comfortable and suits his style. Might get him a red ring next to fully matches his game controller haha
These rings are so beautiful my husband and I couldn't stop looking at them! The green has a hint of blue in it, depending on the angle the light shines on it. The forest engraving is so detailed. Love them.
Let me start off by saying, this is beautiful! It has a tiny, tiny bit of sparkle to it which makes the blue color is absolutely stunning. It’s thicker but not bulky. It feels very sturdy, yet soft and comfortable. Unlike other silicone rings, this does not feel or look cheap.
I had ordered this exact one for my husband before and loved it so much that I wanted one as well. I’d been waiting for Knot Theory to release this in a smaller size (the men’s sizes were way too large) and I’m so glad they did! Hands down my favorite silicone ring!
I wear a size 5 and it fits wonderfully!
Lovely ring, very comfortable fit. The colour is exactly as I expected, it has a beautiful shine to it. Fast shipping as well!
Absolutely gorgeous and comfortable! The color really shows best in the sunlight, but even inside it is gorgeous! Super comfortable, especially since I wear gardening gloves 40 hours a week at work and my actual engagement ring was super uncomfortable under them. Perfect for busy hands!
Very nice, got it for my husband to wear to work so he doesn’t mess up his gold band. He loves it because it’s soft and very comfortable. My husband wears a 10 and I bought a 10 and he says it fits perfectly but I’d say it’s like a hair too big. But definitely not loose enough to fall off or anything.
