This is a 1946 premium from Post Corn Toasties. It is made of luminescent plastic which glows brightly in the dark after light exposure. This same ring design, a few years earlier in 1940, saw use as the Jack Armstrong Dragon’s Eye ring (see item #1439) and features figural crocodiles as each band with the animal’s jaws spread wide open towards the ring top which supports the oval plastic stone in deep red. Bands have a couple of pinpoints of dust in the crevices but this just helps the detailing of the crocodiles show up. Ring is N. Mint and glows intensely in the dark.
