For the truly geeky! A bracelet with the phrase "They Walk Among Us!!" in binary code... Do an Internet search of that phrase if you don't know what it means!
At the moment this bracelet has an inner diameter of 5cm (just under 2"), suitable for a youth or someone with thin wrists, but in SWF this does flex somewhat. It is 3mm thick. If you'd like a larger one let me know.
I can also make another using the phrase of your choice.
