These are Higgins Brothers brand rings. At this point I have one set left, with one yellow ring, one blue ring, and one “red” ring. Note that the “red” isn’t exactly “red”; it is more orange-y. I’d also note that the blue looks darker in the picture than in real life. All the colors are pretty neon-ish. The retail price for a set of 3 would be $16.50 plus shipping.
This item was purchased at a discounted rate for resale to my students. Please read here for an explanation of my sale terms.
