Tritium key chain. Stays lit for 10 years with no charging.

Tritium is a light-emitting device produced by radioactivity of hydrogen isotope tritium. As the tritium decays it releases electrons inside the glass tube which mix with phosphorous powder which produces fluorescence. Tritium does not need to receive electricity or light from the outside world to charge it, it will continue to be self-luminous for 10 years. Tritium’s radioactivity is very weak and if the tube were to break it is harmless to the human body. The phosphorus powder however is only harmful if inhaled. There is a very small amount of phosphorus powder inside the tube.

Case made of plastic.6 colors available.
