ring that i can’t find anywhere online

I was at disney springs one day and saw a ring for Billy (from WandaVision and Agatha All Along) and i didn’t get it, but when i came back it was like it never existed. I’ve tried to look it up everywhere, but it’s like it vanished off of the earth. It was a double ring with a moon on the top of it and i believe it was silver and blue but i’m not sure. can anyone help me find this?
