Have you ever wondered what that tiny pocket - (small pocket on jeans) - on your jeans is actually for? You know, the one you can barely fit your finger into, let alone anything useful. Maybe you've stuffed a coin, a USB stick, or - if you're really optimistic - even a spare apartment key into it. But if you thought it was just a decorative relic of the past, you're wrong! This tiny detail has a rich history that dates back more than 150 years.
