Originally used during the cold war to provide emergency lighting in submarines, these glowing gadgets are a handy addition to your keyring.
The Nite Glowring will help you to locate your keys on the ground, around the house or at the bottom of your bag and it can be attached to almost anything - a sports bag, fishing gear, zipper tag, light pull, a dog collar (the canine, not the vicar) or cat collar to avoid late-night stumbles over your pet. You could even attach them yourself to attract attention in a nightclub or find your mates at a festival. Whatever the use, this exceptional accessory certainly marks the spot.
Vibrant-coloured and acrylic housed the amazing Nite Glowring uses gaseous tritium sealed inside internally phosphor-coated borosilicate glass vials to emit that clever coloured glow.
Inside each Nite Glowring is a single-sealed glass tube, which contains a minute amount of radioactive gas that permanently reacts with a luminescent coating. The resulting light source will glow for 10 years and enables you to see your Glowring from as far as 30 feet away in complete darkness!
