Tritium (symbol T or 3H, also known as hydrogen-3) is a radioactive isotope of hydrogen and one of the most valuable substances on earth, with a market price of 30.000$ per gram.
The Tritium vials used are light sources of gaseous tritium isotope, hermetically sealed in glass.
This radioactive tritium gas glows completely on its own, in a very safe manner, without needing to be 'charged' with light as required by most phosphorescent glow in the dark products. The glow will be subtle and visible in low-light conditions; the darker the better. It will not be visible in daylight or well-lit areas. The light produced is literally ''on'' at all times, it's intensity isn't reduced after a few hours and will last non-stop for about 20 years. This is truly a ''nuclear powered'' item!

Worldwide international shipping, signed-for. Delivery takes 1-5 weeks (1-2 weeks for Europe/ 2-5 weeks rest of the world).
