2.5" square by 1.25" deep mailing box from 1947 General Mills has label intact. Bottom outer flap gone but both inner flaps still intact as well as all other edge flaps. Square 4" (open) instruction sheet is Exc. Ring luster is extremely Fine. Plastic end cap not cracked. No flashing atoms as speck of radioactive material had brief half-life, but with light exposure ring interior will then give off very faint glow in the dark. Instructions and box are quite scarce. Although ring was immensely popular when issued, most boxes and instructions were discarded.
