They recharge quickly by absorbing light from any light source. The brighter the light source, the brighter they glow.
Their original use was as emergency markers, marking survival equipment onboard submarines. The Navy required them to be “non-powered, rugged, re-usable, and non-nuclear”. We use them everywhere including marking camp sites, hanging them from the inside door knobs at hotels to help us find our way out.
Finding and tagging your gear out of a dark cargo hold has never been easier.
Add the UGM to your Backpack, Door Knob, Gas Valve, TV Remote, BOB, SHTF Bag, First Aid Kit. ETC
Even can light up a tent!
Each UGM is made by hand and tagged with a USA Made Stainless Steel Ball Chain.
- USA Made

Great for things that you want to be able to find in the dark. Keys,pets,etc...
It emits a lot of glow after taking it off from an artificial light source and then tapers off a few hours later. When it is left out in the sun it gives off a strong green glow when you take it to the shade, and probably lasts the entire night (I haven't tested it yet but I'll do it soon).
My gripe would probably be the overall durability of the pack itself, as it is encased in a somewhat thick clear plastic, unlike the ones that are coated in resin and shaped in bars which I also bought as gifts :)
Quick delivery by CC too.
This is basically a bunch of "pebbles" that all glow in the dark. If you put it in the sun for about 5 minutes or shine a strong flashlight on it, it is probably the brightest glow maker you'll ever see. They aren't kidding when they say it glows bright enough to be able to read a street sign! Might be good for kids who are afraid of the dark too.
