The ColomPac 141 boxes make work easier and faster for anyone shipping boxes. All boxes are self-sealing, and they have an instant bottom and a tear open strip. The adjustable height with gaps of a centimetre is the best advantage of the CP141 boxes, which eliminates the need for storing boxes of different sizes, since the same base size is usually all that is needed. The height scales to the products, which prevents them from moving and minimises the need for extra pieces. Products in CP141 boxes take less space and reduce the shipping fees.
