She buys those rings from a Chinese website that has tons of shops called Taobao. But since it has thousands of shops, no one can find them. I'm asking some people that use taobao a lot to see if they've found the shop that sells them. Since the shop's in Chinese, it's sometimes hard to figure out the right keywords to search for things. And someone told me that Creepyyeha just found them on accident when she was looking for a good deal on regular O-rings. I'm not sure if that's true or not.
I'll let you know.
