This type of device is used to crush ice cubes into smaller particles, which are suitable for making cold drinks, cocktails, and slushies.
The ice is placed into the top hatch and crushed by turning the hand crank on the side.
The crushed ice is collected in a clear container at the bottom of the device.
Manual ice crushers are often used in home bars and are a hygienic alternative to using a user's hands to crush ice.
