Made from the thinnest of the various width oak staves that are used to construct whisky barrels. These key-rings are 4cm (1.5 inch) in length, 1cm (0.5 inch) wide and 2cm (0.75 inch) deep, are threaded with 1mm para-cord, and lightly sealed with Danish oil to bring out the character of the oak. To reflect the dominoes that I also produce these key-rings are made in the shape of a double-blank domino. During the game of dominoes this piece is a wildcard, to be used at any time, so having this in your pocket will keep you ahead of the game.
