Cold knowledge about clothing (jeans article)

In the pocket on the right side of our jeans, there is often a mini pocket. What is this pocket used for?

When jeans were first invented, a cloth merchant named Levi Strauss made them for American gold miners to hold pocket watches that they carried with them to check the time, in case the watches were lost or scratched. Therefore, this laughing square bag is also known as the "watch bag".

Later on, jeans became popular and this small design has been preserved. Full of design sense and fashion, people can also put some small items that are easily overlooked, such as coins, keys, and so on.
