Chainmail pocket fidget gadget. Would also make a nice pendant.
In doing cons/shows, we've found many folks enjoy the feel of chainmail. It's soothing. We've had kids spend time at our booth petting some of our wares and grateful parents letting us know that it was a helpful time out. So we created these easy to carry, fidget gadgets. These can be fiddled with discreetly and make no noise.
