The Keyois Capsule was designed with a tritium centerpiece in mind, however for legal reasons we cannot sell tritium vials assembled in capsules. They are not likely to come ‘back into stock’ anytime soon.
If you have your own tritium centerpiece you can buy an unassembled capsule and with some tools and work do the finishing touches yourself. See the FAQ page for more information.
Out of stock
Tritium vials are completely safe. The inner surface of the vial is coated with a phosphor which reacts with the tritium gas which fills the vial, causing a glow.
