About Nugget Ice:
The COWSAR ice maker produces soft, chewable nugget ice, also known as pellet ice. This type of ice is known for its unique texture, which is softer than traditional hard ice cubes, making it enjoyable to chew and ideal for various beverages as it chills drinks quickly and melts slower.
