I've got a bag of glow in the dark zip ties I bought at Conrad Electronics (A Germany Based electronics company). I think they are about 8 inches long and a quarter inch or less wide. I don't think you will find tritium zip ties. Each tie would be expensive and subject to breaking.
Let me know if you need a bag or two of the GITD zip ties.
Could you give me a link to where I could find more info about these. I looked over conrad electronics but couldn't find em. Im interested in how long they glow for and also price and quanity in each package. Thanks
The reason you won't find tritium zip ties is that tritium itself is not luminous. It is combined with a phosphorescent outer coating that puts off colored light when irradiated. This would require some [expensive] engineering (and production) to create a maleable and durable ziptie that wouldn't leak tritium or chaff away the phosphorous mat'l.
Better off searching for existant GITD zipties.
