The box is 74 mm square and 140 mm long. Inside the box is an inner liner and within that liner is a pasteboard frame that holds the valve and the soft wadding that keeps the valve secure. In the space formed between the outer and inner walls is located the data-sheet. The paper over the base of the box can be seen through and it reveals that the original purpose of this carton was to hold a CT25.
