sayram 2pcs Glass Luminous Tube, Rare Earth Luminous Stick, Glow Bar in The Dark Tril Vial Alternative, DIY for EDC Accessories Decoration

These things glow for about 20 minutes total. I charge them with a hard core black light and it fades in minute's. Definitely not worth it. Especially at this price. Maybe if it came with 10 instead of 2. But still doesnt serve the purpose its supposed to

Very dim, as in hardly visible in the dark, even after immediate charging. Otherwise as expected.

This little tube is packed with glow in the dark powder comes well packaged in a plastic bag and sample vial. Exposing the tubes to if light to charge yielded a rather bright response inline with other premium glow powders.For anyone buying this even actual tritium doesn't glow this bright if you want bright like the movies you are going to need electricity and leds.
