Interesting facts

Buttons and button-like objects used as ornaments or seals rather than fasteners have been discovered in the Indus Valley Civilization  as well as Bronze Age sites in China and Ancient Rome.
Buttons made from seashell were used in the Indus Valley Civilization for ornamental purposes. Some buttons were carved into geometric shapes and had holes pierced into them so that they could be attached to clothing with thread.
Functional buttons with buttonholes for fastening or closing clothes appeared first in Germany in the 13th century. They soon became widespread with the rise of snug-fitting garments in 13th- and 14th-century Europe.
