The SpinTi by COMANDI is a compact everyday-carry accessory designed around a continuously illuminated tritium core. Measuring 35 millimeters in length and weighing 8 grams, the keychain is machined from Grade 5 titanium and features six tritium vial slots housed within a rotating body. Unlike battery-powered lights, the tritium system produces a constant glow through radioactive decay interacting with a phosphor coating, eliminating the need for charging or activation. The skeletonized titanium exterior exposes the illuminated core from multiple angles while maintaining a lightweight and durable construction.
A solid-state pivot allows the outer shell to rotate around the core, giving the accessory an additional tactile function. The design uses a metal compression system to secure the vials without relying on rubber components or adhesives. SpinTi can be attached to keys, bags, zippers, or worn as a pendant, while a hardened glass-breaker tip adds emergency functionality.
