These cufflinks offer a novelty of design in that they incorporate real liquid levels, recreating those which are used by engineers and construction workers. These cufflinks can be given as a gift to an engineer or construction worker which you know, as a joke, or you may even decide to purchase a pair for personal wear, as there is sure to be no shortage of comments on your crazy, original cufflinks. The thin, capsule-shaped design is quite elegant in itself, and you can enjoy getting away with wearing these jokey cufflinks to all kinds of stuffy, formal occasions, in rebellion.
