The Prison Key Rings from Jack Spade are the sort of thing you give, as a gift, to people who already have absolutely everything or just like to collect oddities. The handbraided horsehair knot tassels are made by inmates in a Montana prison. Each is threaded onto a 1.5" ring engraved with the Jack Spade logo. The tassels are 5" long and are available in a variety of colors, although you don't get to pick which color yours will be. Price: $75.
