The latest iteration in these popular items, the Mk. VIII models feature a new ball locket casing, made of a superior crafted alloy. Split rings replace the older jump rings, and both the 12mm lobster clasp and the rings are plated with 18k gold. The internal LED device is still powered by a 1025 button cell, included with purchase. Finally, these can also be worn on an included 30-inch rat-tail cord.
These items come in more colors as well, and are available on request.
They are still sold for the same low price of $18 USD each, plus additional shipping.
