Buttons first appeared in India. Archaeologists once found amulets with two holes carved out of shells in the Indus Valley. This may be a button from before 3000 BC. It was only 1,000 years later that Scottish residents began to make coal jade buttons.
Jeans first appeared in the western United States. In order to be durable, yellow metal zippers and rivets were used. Over time, it became a traditional style feature of jeans.
With the deepening of people's understanding and the pursuit of beauty, people later used buttons mainly as decorations, followed by practical products for connecting fasteners. Driven by the beautification and decoration functions, the materials of the buttons began to diversify during this period.
