I saw the refill thing , but im not sure about spending $20 for another set when i have one of them alreadyNo, you can get a replacement from T11. $20 will get you a new gimmick and a new ungimmicked ring. Look in your refills section.
Buying the rings themselves form other websites is expensive , (i did the reasearch)I don't know for sure. I haven't heard anything about ordering just one ring. You could ask them. But the ring is Tungsten carbide, so any price is good (that's what I'm told).
