These dry ice pellets have a diameter of 16mm and an average length of 50mm. As they are much larger, they last much longer than the 3mm pellets. These pellets are double compressed in our state-of-the-art dry ice machine, and as a result are extremely dense. They are highly effective in the transportation of any kind of temperature sensitive goods which must be transported at the correct temperature to ensure product integrity. These pellets are also useful for creating a smoky special effect for parties, catering and movie shoots and are fast becoming an essential for longer camping and fishing trips.
