This unique "mono-goggle" was designed by the Armory for a man known only as the Keymaster of Kent. To his specifications, the eyepiece is fully adjustable and fits securely around the head. The alchemically-treated lens aides in low-light vision. The gold-patterened suede was part of a special lot, willed to the Armory by the pirate captain Vane Kilgrave, and the emblem on the temple was a special request by the Keymaster himself.
Sadly, due to debts to some of London's more unscrupulous criminal kingpins, the Keymaster was never able to pick up his order. As is Armory policy, this incredibly unique fabrication is now available to the public at the price of $50.00.
