If you are a developer, programmer or some one who spends more time behind the desk but has occasional bursts of "human interaction" where you need to dress right, the emergency cufflinks can save your day.

Pretty easy to use and carry, the emergency cufflinks, which cost about UKP 7.99  are embedded in the  thickness of a typical credit card so  they can be carried in wallet. To use, just twist them out of the sheet and fold to lock the cuffs in place. Keep the spare pair for next time. 

We wonder what will they think of next. Emergency underwear made of paper? :)
