Swizzle sticks, also known as STIRRERS, are a type of barware used to mix drinks. They are typically made of plastic or wood and have a flat end and a spiral end. The flat end is used to stir the drink, while the spiral end is used to create a decorative pattern in the drink. Swizzle sticks are often used in cocktails, such as the popular Mojito, and can also be used to garnish drinks with fruit or other decorations.
