We use the following everyday items so often that we're certain we know everything about them and their functionality.
However, with a closer look, you might find that your favorite items were designed to fulfill more purposes than you thought. From the metal button on your jeans to takeaway cup lids, here are some everyday things that have hidden features you never knew about.
Little Jeans Pocket
Many models of denim jeans come with a ting extra pocket on the side, known as the fifth pocket. People have found different uses for it, such as for cash, small change, or a stick of lip balm, but this small pocket was intended for something very specific – the pocket watch. Back in the 1800s, the pocket watch was a common accessory and was one of the most important and expensive items people kept on themselves, and the fifth pocket was designed specifically with them in mind.
