They aren't edible, but they are colorful and look like candy. Each cock ring has knobs or "spikes" around it to give your partner extra stimulation. In their un-stretched shape, they're small enough to fit snugly around a pinky finger, but they are made of a remarkable stretching material that can expand to a much larger diameter. Once taken off, the ring will slowly contract back to its original size again. Therefore, one size fits all. Sold separately.
